Sounds 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. Here are more opinions and answers from other FAQ Farmers: * In my experience, calcium chloride melts ice fastest. Cat litter doesn't dissolve, so it obviously can't lower the freezing point of ice. * 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.

Sodium chloride melting point reduced by adding calcium chloride?
Yes, a mixture containing 42% NaCl and 58% CaCl2 melts at about 590 Celsius while pure sodium chloride melts at about 800 Celsius.
What two properties of sucrose distinguish it from sodium chloride?
There are several properties that distinguish sucrose from sodium chloride. One is that sucrose melts at around 186ºC whereas sodium chloride melts at around 800ºC. Another property would be that sucrose is a non electrolyte (will not conduct a current when in solution) whereas sodium chloride is an electrolyte and it will conduct a current when in solution.
Is heating sodium chloride a chemical change?
Heating is a physical change. Nothing new is formed
Commercial use of sodium?
Pure sodium? A lot of engines have "sodium cooled valves." They drill out the valve stem and fill it with metallic sodium, which melts at a low temperature. After the sodium melts, it sloshes around in the valve and pulls the heat away from the valve face, making the valve last longer and work better.
Which element has a higher melting point potassium or calcium?
Calcium at 860 degrees celsius potassium melts at a mere 65 degrees celsius
Sodium chloride melting point reduced by adding calcium chloride?
Yes, a mixture containing 42% NaCl and 58% CaCl2 melts at about 590 Celsius while pure sodium chloride melts at about 800 Celsius.
What temperature melts chloride salt melts?
The melting point of sodium chloride is 801 0C.
What are the differences and purposes of the different types of ice melt such as sodium chloride, potassium chloride, calcium chloride and blends?
Ice Melts are for minimal damage being substained by winter conditions to your lawn.
Why is sodium chloride placed on icy patches on highways and on steps in the winter?
Sodium Chloride is an impurity so it inreases the melting point and reduces the boilin point of the ice, thus the ice melts at a faster rate
What happens when sodium chloride melts?
It goes from the solid state to the liquid state.
Which salts melt ice faster?
rock salt melts ice faster because every winter my mom puts rock salt on ice and it melts within 2 seconds so i think rock salt melts the fastest

What melts road ice?
Potassium Chloride is the most commonly used "salt", but Calcium chloride is next in line.
Does sodium chloride turns directly to vapour on heating?
No. Sodium chloride melts at 801 C at standard pressure and does not vaporize until it reaches 1413 C.
Why doesn't salt melt in the heat?
It does. Salt, or sodium chloride, melts at 801C or 1474F.
Is heating sodium chloride with a Bunsen burner a chemical change?
No. It is a physical change. It only melts.
