Which of these melts ice most efficiently calcium chloride catbox litter sodium chloride rubbing alcohol mineral rock salt or melting crystals?
Efficiently Melting Ice \n. \nSounds like a great question to be answered with an experiment. Take equal amounts of ice in identical containers at the same temperature, sprinkle each set of ice cubes with equal amounts of the different substances, also at the same temperature, then observe which …container of ice cubes melts the fastest.\n. \nHere are more opinions and answers from other FAQ Farmers:\n. \n . In my experience, calcium chloride melts ice fastest. Cat litter doesn't dissolve, so it obviously can't lower the freezing point of ice. \n . \n . We did this experiment for school. We found out that calcium chloride did work the best, but rubbing alcohol and rock salt worked well, too. We also found out that the cat box litter did not work at all. All it did was absorb all the ice and water and make a big ice chunk. (MORE)
Sodium chloride is an ionic compound that has a crystallinestructure. Each sodium ion (Na+) interacts with 6 chloride ions(Cl-) on each side of it, and each Cl- interacts with the 6 Na+around it. In a single salt crystal, there are millions andmillions of ionic bonds. To melt an ionic material, you …have tobreak each of those ionic bonds. Ionic bonds are not that weak, andwhen you try to break all of them it takes a lot of energy! Ioniccompounds are different than molecular ones in this way. To meltice, for instance, you don't have to break the bonds in water, youjust have break the much weaker attractive forces between two watermolecules that are next to each other (called intermolecularforces). These types of attractive forces are much easier tobreaker than ionic bonds, and so most molecular compounds havelower melting point than do ionic ones. Most ionic compounds havevery very high melting points in fact. (MORE)
Answer . Because that is what it is made of. Chemical formula is NaCl. 1 gram of salt has 0.3933 grams of sodium and 0.6067 grams of chlorine.
The melting point of sodium chloride ( NaCl ) is 801 Â°C, 1074 K, 1474 Â°F.
Calcium chloride because when it is mixed or come is contact with water the hydration energy of calcium chloride is extremely exothermic thus emitting high amounts of thermal energy , also calcium chlorides is much stronger electrolyte which contributes to its de-icing abilities.
The melting point of sodium chloride is 801 0 C. The boiling point of sodium chloride is 1 413 0 C.
Yes Soduim chloride is salt salt. salt water has a lower freezing point. In many places salt is put on roads and footpaths to expedite the melting of ice.
because sodium chloride is an ionic bond and so it is a very strong bond. So it takes alot of energy to break the bonds between the atoms.
the bonds between the atoms of carbon in diamonds are much strongerthan the atoms in Sodium Chloride. Each carbon atom in diamond iscovalently bonded to 4 other carbon atoms making it very difficultto boil/melt. Whereas sodium chloride is in the structure of anionic lattice with strong electrostatic… forces of attractionbetween the negatively charged chloride atoms and the positivelycharged sodium atoms; this is still strong but not as much asdiamond.

801 degrees Celsius This is incorrect.! Actually it has a boiling point of 1413 degrees Celsius or 2575 F.
The melting point of sodium bromide (a salt) is 755 . Calculate this temperature in and in kelvins.
it is because the charge of the magnesium ion is 2+and oxide ion is 2- they attract each other more strongly than sodium ion is 1 and chloride ion is 1-.
Melting point of sodium chloride is 801 0 C. Boiling point of sodium chloride is 1 413 0 C.
A salt solution contains salt (sodium chloride) and water. If you want to separate the salt from the water, you need to boil the water. When the water is boiled, it will form a gas and leave the salt solution. (It doesn't need to be boiled, and could be left to sit in room temperature where the wate…r can evaporate). Therefore, the salt is left behind and is separated from the water. (MORE)
Salt is made of sodium (Na) and chlorine (Cl). When these two elements bond, you get sodium chloride (NaCl). Otherwise known as table salt.
The melting point depends on the number of water molecules (x) in CaCl 2 .xH 2 O 772 Â°C (anhydrous) (x = 0) 260 Â°C (monohydrate) (x = 1) 176 Â°C (dihydrate) (x = 2) 45.5 Â°C (tetrahydrate) (x = 4) 30 Â°C (hexahydrate) (x = 6)
714 Â°C (987 K) on rapid heating. Slow heating leads to decomposition from 300 Â°C
The sodium chloride density is 2,165 g/cm 3 and themelting point is 801 0 C.
Sodium Chloride has a higher melting point because at room temperature it is a solid but Ethyl alcohol has already melted, as it is liquid.
CaO - the attraction between a 2+ and a 2- ion is much stronger than between a + and a -. .
No. It is only a chemical change if the properties of the atom (or in this case ionic compound) are completely changed. This means anytime a chemical bond in that molecule is broken or formed, it's a chemical change.
Yes , as soon as solid sodium chloride reaches 801 Â°C (1,474 Â°F), its molecules can't hold together anymore, and fall apart into a liquid.
There is no definite answer to this, as the surrounding temperature will ultimately determine when the ice will melt. Also, salt and sodium chloride are essentially the same; however, salt will more effectively lower the freezing point of water, causing water to be in its liquid state until around 2…9 degrees, or so.

During heating the internal energy is increased, the ordering ofthe chemical entities in the crystal lattice is destroyed and thesubstance is melted.
Yes, a mixture containing 42% NaCl and 58% CaCl 2 melts at about 590 Celsius while pure sodium chloride melts at about 800 Celsius.
Because NaCl is an ionic compound. NaCl is formed by sodium and chloride ions. Unlike covalent bonds, these are electrostatic ionic bonds. It requires a massive amount of energy to break them.
Aluminium oxide, because it has a very strong giant covalent structure that takes a lot of energy to break.
Sodium chloride is extracted from salt mines or sea water and afterthis is purified to become table salt.
At high temperature the internal energy of a material is increased;consequently the ionic or molecular ordering is damaged and thematerial become liquid - a phase with little ordering.
The ionic bonding in sodium chloride is much stronger than the internal bonding in either element that forms sodium chloride; therefore, the melting point of the salt is much higher than that of either element that forms the salt.
NaCl is an ionic bond(Metal and non metal) The intermolecular bonds are much stronger. Ammonia (NH3) is a covalent bond (Non metal and non metal) The covalent bonds are weaker...so it's easier to break
Sodium Chloride is an ionic compound, thus it will break up into positive sodium ions and negative chloride ions that can break the hydrogen bonds that hold water molecules together in the solid structural lattice. Sucrose will melt water, but it will not melt it as fast because it is a covalent com…pound, not ionic, so it will not break hydrogen bonds as effectively as salt. However, sucrose is a polar molecule, and likes dissolve likes, so it will be dissolved by water and thus melt the ice, but it takes longer. (It's funny because I just did an experiment with melting points of iced tea ice cubes versus water ice cubes for my natural world class and our data supported this... easiest lab I've done in my career as a bio major haha) (MORE)
At 20 0 C a water solution with a sodium chlorideconcentration higher than 36,09 g/100 ml is a saturated solution.
Chloride is not substance that can be isolated but an negative ion that needs to have its charge balanced by a positive ion. Compounds containing this ion are called chlorides, their melting points vary. The element chlorine has a melting point of -101. 5 degrees Celsius, which is equivalent to… 171.6 Kelvin and -150.7 degrees Fahrenheit. (MORE)
Because NaCl is an ionic compound. Sodium chloride is formed by sodium and chloride ions. Theseions attract each other alternatively by electrostatic ionic bonds. It requires a tremendous energyto break them.
Sodium chloride is not a hydrated salt; but in special conditionsthe dihydrate NaCl.2H 2 O exist.
CaO has a double bond since there is a transfer of two electrons from the calcium to the oxygen. NaCl only has a single bond. Also, the EN difference between Ca and O is greater compared to that of Na and Cl. This means there is a greater dipole-dipole force (polarity) present. Basically, it has a s…tronger attraction between its cations and anions. (MORE)
Sodium chloride has a high melting point for a few reasons. Sodium chloride is held together by ionic bonds, and ionic bonds are very strong (as compared to covalent bonds, which are relatively weak). The higher the bonding strength, the more heat it will take to break those bonds to create a liquid…. Thus, sodium chloride has a high melting point because of the strong ionic bonds it has. (MORE)
The sodium ion has a 1+ charge and the chloride ion has a 1- charge. By comparison the magnesium ion has a 2+ charge and the oxide ion a 2- charge. Because the charge difference is greater in magnesium oxide, the forces of attraction between the ions are greater. This makes the ions harder to mo…ve from their positions which is what happens when a substance melts. Additionally, the magnesium ion is smaller than the sodium ion and the oxide ion smaller than the chloride ion. This increases the density of the charges and makes forces of attraction even stronger. (MORE)
because sodium chloride is a crystalline solid so its melting point is grater than hydrogen chloride
Dissolving sodium chloride in water heat is released and thefeezing point of water is lowered.
Because it is the salt found in the sea water. And the life started in the sea (ocean)
The heat of dissolution for calcium chloride in water is greater compared with the same paremeter for sodium chloride; consequently the process of dissolution need more heat from the environment and the freezing point of the water solution is lower.
It has got to do with the intermolecular (forces in between different atoms) forces. Iodine (I 2 ) has weak intermolecular forces in between molecules, called a dispersion force. This force is very weak, resulting in lower boiling and melting temperatures. This happens for all covalent bonded non-me…tals. Sodium Chloride, however, has a very strong intermolecular force. This is because they are Ionic (Metal and a Non-Metal). Ionic compounds are like a bar magnet, with the metal (Sodium) as the positive end and the non-metal (Chlorine) as the negative end. These form a 3D lattice Structure (a Cube Structure). The positive ends attract to the negative ends and vice versa. This strong attraction means that when the substance is heated up, the molecules want to stay together. This results in a higher melting and boiling temperatures. Note: Ionic forces are about 1000x stronger than dispersion forces (MORE)
