Question

The boiling point increase and freezing point decrease when sodium chloride is added to water. Explain​

Answer 1

Answer:

If you add salt to water, you raise the water's boiling point, or the temperature at which it will boil. The temperature needed to boil will increase about 0.5 C for every 58 grams of dissolved salt per kilogram of water. This is an example of boiling point elevation, and it is not exclusive to water. It occurs any time you add a nonvolatile solute such as salt to a solvent such as water.

Explanation:

When you add salt to water, sodium chloride dissociates into sodium and chlorine ions. These charged particles alter the intermolecular forces between water molecules.

Answer 2

Answer:

sodium chloride is a non volatile solute. when a non volatile solute is dissolved in a solvent, it's vapour pressure decrease and as such it's freezing point decrease and boiling point increases.
