I know it doesn't really have anything to do with anything we're doing now but something, a question in fact, came into my head due to recent weather activity.
Is the process that makes salt dissolve in water the same as the process that makes salt melt ice? or is it something completely different?
I know it's not particularly constructive in terms of organic chemistry or enthalpy but it's been playing on my mind.

Steve, I'd alwatys been told it was slightly a different way round: salt is a preventative measure, as salt water has a lower freezing/melting temperature then 'normal' rain water.
well it decreases the melting point and makes ice melt back into water which is why its used to deice raods in conditions like the current.
what i wanted to know was why and how it did so.
