- why salt lowers melting point of ice?
Main Question or Discussion Point
There was a question on "Why salt lower the freezing point of water?"I found the following answer."Thermodynamics teaches that a loss of entropy can be overcome by a gain in so called enthalpy". The loss of entropy by freezing the solution canbe over come at temperature much below 0 degree C because the gain in enthalpy by freezing water rises when temperature goes down."How can there be gain in enthalpy by freezing water instead of loss? I presume that the gain in enthalpy refers to gain by environment.Please confirm.
