Lab report for How does adding salt affect the freezing point of water

Answer 1

salt lowers the freezing point of water.

Answer 2

yes,@abb0t is right.

Answer 3

Thank you.

Answer 4

Salt molecules bond with water molecules, making it more difficult for ice to form. The result is a solution with a lower freezing temperature. The more ions that are present the lower the freezing point will be in turn. Sodium ions in salt water disrupt the crystallization, freezing process.

Water freezes (and melts) at 0°C (32°F).

When you add salt to water an endothermic reaction occurs, the solution takes heat from the surroundings to dissolve the added salt.
