Salt will melt ice faster than the same amount of sugar because there are more molecules in salt than there are in sugar. It is the colligative property of salt that makes ice melt...
Salt melts ice because it lowers the freezing point of water.
(Note: If you're already familiar with chemical potentials, you may be interested in
this alternative thermodynamic explanation.) Two things happen when ice and ...
Salt melts ice by lowering the freezing point of the water around the ice. The ice
melts and is unable to re-freeze except at a much lower temperature. Thomas ...
If you put salt
in a situation where the temperature will never get up to the new freezing point of the salt
-water solution, you won't see any benefit. If you just want to see an example of how cold ice
can get, mix 33 ounces of salt
with 100 ounces of... More »
