What is free chlorine and total chlorine?
Chlorine in water may be present in two forms, free and combined. Free chlorine does the hard work of killing bacteria and oxidizing contaminants. When you add chlorine to water, you are actually adding free chlorine. When the free chlorine combines with contaminants, it becomes combined chlorine, or chloramines. In water, this form of chlorine has very little sanitizing ability, and no oxidizing ability. Total chlorine is just the sum of both combined chlorine and free chlorine.
Which measurement you use, free or total, depends on your testing needs.

Free Chlorine is the Chlorine which is free to do its work in the pool, as opposed to Combined Chlorine which is chlorine that has combined with contaminants and is tied up and ineffective as a sanitizer in the pool. Sometimes you will see it abbreviated as FAC, which stands for Free Available Chl…orine. (MORE)
Answer . \nDon't add so much chlorine. It will go down in a day or so.
1) Just don't do anything leave it alone (the chlorine will eventually drop, high amounts of sunlight and a high bather load will speed up the process 2) You can add chemicals to the pool 3) Replace some of the pool's water to fresh, clean water
Chlorine is the chemical element with atomic number 17, atomic weight 35.453 and symbol Cl. It is a natural element, a yellow green gas at a room temperature. It is heavier than air, but under the correct pressure and temperature it can be converted into liquid. Chlorine is found the earth and ca…n also be found in the sea. It is essential to the life of animal and plants. (MORE)
Total Residual Chlorine (TRC) is the total of free available residual chlorine and combined (bound) residual chlorine. The amount of measurable chlorine remaining after treating water with chlorine i.e. amount of chlorine left in water after the chlorine demand has been satisfied
Technically no. Your total chlorine reading would include all forms of chlorine, which we tend to lump into to basic categories, Free and combined. If you get readings that show that the free amount is higher then total, I would suggest a retest. If you are still getting the same result, I would try… another test or different reagents. I'm sure there might be something that could give you false results and that might be what id happening in this case. Actually it can happen because it happened to me today i saw it happen that the free chlorine was 2.49 and after the 2 minute waiting period the test was 0.33 and the sample was visibly less pink than when the DPD 1 was tested, there has to be some reason for this or some way to fix it as if we are using the same reagents for other samples and it is working for those then this must mean that there is something wrong with the water i a, testing and not the tablets i am testing with! The total reading after time will drop if the residual level is high enough and there is not enough DPD. Hach recommends for using a 5 ml sample instead of 10 ml and 2 power pillows instead of 1. This gives four times the DPD to do the analysis. With very high levels you can see a flash of dark color and then go to clear as the chlorine bleaches the color from the DPD. The addition of extra DPD overcomes the bleaching effect. (MORE)
Basically total clorine in a pool is the total clorine that is in the pool (even the part that has been used to oxidize various contaminants). Free clorine is the total amount of clorine available to be used as an oxidizing agent. In a clean pool these amounts should be the same but as a pool accumu…lates contamanents the amount of total clorine will be higher than free clorine. It is best to shock the pool to eliminate all contaminants and get the total and free clorine levels back in balance. (MORE)
Drinking water is chlorinated to avert the risk of harmful micro organisms causing ilness in the public through drinking water. It is also used to keep swimming pools safe.
Free or residual chlorine is chlorine that is present in the form of hypochlorous acid, hypochlorite ions or as dissolved elemental chlorine.. Bound chlorine is that fraction of the total chlorine that is present in the form of chloramines or organic chloramines.. Total chlorine is that chlorin…e that is present in free or bound form, or in both forms.. In water treatment, free/residual chlorine is the amount of chlorine that is still available to do its job of disinfection. Bound chlorine is chlorine that has been used up. It is still in the water, but it is no longer available for disinfection. (MORE)
Free chlorine gas combines with other elements and compounds to kill living cells. That's why it is used as an anti-bacterial agent for surfaces and swimming pools. It was one of several gas weapons used in World War I. As a potent chemical reactant, it is widely used in bleach (sodium hypochorite)… to remove organic stains, as from dirt or grass. In forming dilute hydrochloric acid, it frees oxygen that attacks the pigments, so it will also remove colors. (see related link) (MORE)
Try a water conditioner, designed to help your water hold on to chlorine longer. Sometimes a non-chlorine shock can help condition the water to help stabilize your chlorine levels. Could be high heat, phosphates, nitirites, nitrates, or aggressive water. If it's cloudy, a little green, a serious dos…e of shock may be enough to stabilize it. (MORE)
As long the pool is sanitized in other ways. There are several other ways a pool can be safe and not use chlorine.
You need a test kit to determine free chlorine levels. To reach those levels you test the water and add chlorine until you achieve the required amount ( 1.5 to 5.0 ppm) of chlor. The first reading on the kit is available chlor. The second part of the test would determine the free chlor level. The fr…ee chlorine is what is doing the sanitizing or killing of bacteria. The first reading only tells you that you have some chlor in the water. It is probably not safe to use the pool if you do not have a sufficient amount of free chlor. k (MORE)
Chlorine= Cl 2 idk exactly what that formula means but thts the chemical make-up for it. it has the atomic number 17 and is in halogen group on the periodic table if that helps any. hope i helped y'all at least a little
Total Chlorine = Free Chlorine + Combined Chlorine. or, put another way. Total Chlorine - Free Chlorine = Combined Chlorine. Free Chlorine is the chlorine that is doing its job.. Combined Chlorine is the chlorine that has combined with contaminants such as nitrogen. It is ineffective as a sani…tizer and it is noxious.. Total Chlorine is the total of these two levels.. To eliminate the Combined Chlorine (making all the chlorine in the pool Free Chlorine) you must shock the pool to remove the contaminants. You must reach "Breakpoint Chlorination" , which is the addition of chlorine to your pool equivalent to the Combined Chlorine level times 10.. example:. Total Chlorine = 1.5ppm. Free Chlorine = 1.0ppm. So, the Combined Chlorine (the difference between the two tests) is .5ppm. Breakpoint chlorination, in this example would be .5ppm X 10 = 5ppm. So, in this example, you would add enough chlorine to your pool to raise the chlorine level up by 5 parts per million.. (MORE)
Put less chlorine in or turn the chlorinator down if you have a salt water pool the chlorine that is already in the water is dissipating all the time, so you don't have to worry about that. IF you need to reduce the chlorine level immediately to conform to a certain standard then you can add sodiu…m thiosulfate to bring it down to where you want it. This is if you don't have the time to wait a day or a week for it to come down on its own. I've seen chlorine levels so high it took a month for it to come down to normal on its own. (MORE)
Chlorine can make your pools be better because if you put chlorine in a pool it will make any diseases that people have not be able to be passed aroundin the water.

Chlorine is not a who it is a 'what'. Cholorine is a chemical put in water to purify it and keep it clean.
Not a proper sentence, but I'll awnser it anyway. Chlorine is a pale yellow gas, known for its toxicity. It is in the halogen group of the periodic table, and thus is very electronegitive and very reactive. It can be made by the action of hydrochloric acid on manganese dioxide: 4HCl+MnO2 -->… MnCl2+2H2O+Cl2 (MORE)
my free chlorine level is way to high above ten my pool is 12 by 24 what can i do to fix it
A good way to lower chlorine is to give it a day without the cover in the sunlight. The sunlight will lower your chlorine significantly.

Chlorine gas is poisonous for humans. It can restrict the movement of the diaphragm in the thoracic cavity which can keep us from breathing. Chlorine combine with sodium metal in specific proportion to form table salt.
Many people install salt water systems under the impression that it is chlorine free. Salt water systems produce chlorine electronically and therefore does not require adding chlorine to the water physically. So salt water is not chlorine free water. There are alternative pool sanitation systems th…at use an advanced oxidation process, combined with copper ionization to sanitize the water. These oxygen based systems do not produce any chlorine. These systems produce 100% chlorine free water. (MORE)
chlorine, since its an element. i suppose if you want to go deep enough it has protons electrons, neutrons, quarks, and all sorts of other sub atomic particles. If your talking about bleach or pool chemicals look at the list of ingredients.

Chlorine is a member of the Halogen group of elements. Under standard conditions of temperature and pressure Chlorine is a highly reactive yellowish green gas. It is a di-atomic element, number 17 in the periodic system: Cl 2
i not for sure where you can get gas chlorine, but if you want the kind of chlorine that goes into your pool and cleans to, just go to your local pool store and I'm sure that they have pleanty for you needs.
it could damage skin tissue if submerged too long. like after a long swim in the pool and your skin is all leathery. you can also lose tooth enamel if drank too much. it is about 12% bleach I think.
There are 3 components to the chlorine level in the pool. Total chlorine, Free chlorine, and Combined chlorine. Free chlorine is the chlorine available for sanitation.

You'll need to shock the pool or super chlorinate it. Shock treatment to kill off any nasties & return the Cl level to correct, then resume normal dosing & testing. NB: test & if necessary adjust the pH first. Non-stabilised chlorine breaks down rapidly in sunlight, so if not already doing so yo…u may consider using stabilised chlorine compounds - but don't overdo the stabiliser if added separately because that can accumulate over a long time and reduce the chlorine's effectiveness.

You need to shock the pool. The difference between Total Chlorine and Free Chlorine is tied up and it will be cleared by shocking. Thatis the purpose of shocking.
when you first add chlorine to water it reacts with the ammonia, already present in the water. This reaction forms Chloramines. The chloramines then attack any demand in the water (such as organics or inorganics, organisms). This is the total chlorine residual you are measuring. After all of the de…mand has been meet, the excess chlorine the will then start to oxidize out the ammonia. This is known as breakpoint. After, all the ammonia is oxidized out any remaining chlorine is free chlorine residual. (MORE)
Shock it follow directions on the package and make sure no one swims until the chlorine is at a safe level 1-3 ppm (parts per million)
Yes, but you should shock it so the water stays clear (do not go in after shocking until the chlorine is at a safe level 1-3ppm)
Get a new test kit or new test reagents. Total Chlorine is the measure of free and combined chlorine, therefore the free chlorine cannot be higher than the Total Chlorine. You can't put 10 gallons of water in a 5 gallon bucket.
Add more chlorine. More to it than that. Test & if necessary correct the pH first - that's important. Calculate correct dose rate of chlorine & add accordingly. If it's an outdoor pool switch to stabilised chlorine if not already using it.
It's a poison. Most people can tolerate a low concentration of that poison on their skin. But germs cannot easily live in chlorinated water.
Chlorine does not exist as seperate atoms as it often tends be stable by obtaining an electron from another atom. However, the element chlorine exists in free state as gaseous chlorine molecules.

You scrub the pool and filter the water. Or scrub the pool and do a water change. Some people use salt as an algae inhibitor and they do make salt for pools. You can get it at Walmart or home improvement stores, or at pool stores.
When chlorine is not chemically bonded to another element, it takes the form of a poisonous green gas (which was used as a weapon during WW I, although it was found not to be poisonous enough, and other, even more poisonous gases were developed). When chlorine is in a chemical compound the result is… often a type of salt, including the most familiar type, table salt, also known as sodium chloride (NaCl). Pesticides such as DDT are organic molecules which contain chlorine. The extremely dangerous herbicide, dioxin, is a compound of chlorine and oxygen. It is one of the most toxic substances known. So, lots of different compounds can be made with chlorine. (MORE)
Chlorine is extracted from the salts. The most common salt is used for making chlorine is sea water. The sea water mostly consists Sodium chloride.
no, but it may burn your eyes a bit, so it is better to keep countbelow 3 ppm
