Why Does Salt Melt Snow & Ice?
It is common knowledge that salt can melt snow and ice. The relationship of salt to other properties is fascinating: The salty oceans freeze at lower temperatures than fresh water; salt added to frozen roadways helps to thaw them out; and salt can even be used to make ice cream. While the effects of salt on frozen water are well known, the reasons for these effects remain a mystery to most people. Let’s further explore the properties of the mixed salt and water particles that are responsible for the melting effect.
