Why Does Salt Melt Ice? Understanding How It Works

You can demonstrate the effect of freezing point depression yourself, even if you don't have an icy sidewalk handy. One way is to make your own ice cream in a baggie, where adding salt to water produces a mixture so cold it can freeze your treat. If you just want to see an example of how cold ice plus salt can get, mix 33 ounces of ordinary table salt with 100 ounces of crushed ice or snow.
