There have been threads on the snow melting properties of salt, but I’m curious about how it actually works.
What I know about it is that it reduces the temperature at which the transition from liquid water to ice occurs. Is this primarily by stabilizing the bonding of liquid water, destabilizing the bonding of ice, or both, or am I totally off base? Also, does the addition of salt change the heat of fusion (how much heat per gram of water at its freezing temp you need to remove to get ice) as well?
