What will happen to the boiling point and freezing point of water when some common salt is added to it?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. Boiling point elevation, freezing point depression.

  • When common salt is mixed with water there is an elevation in the boiling point and depression in the freezing point.
  • The presence of soluble salts increases the boiling point of water because the soluble salts absorb the heat supplied to boil the water.
