Question

Explain why -

(i) common salt becomes sticky during the rainy season?

Answer 1

Common salt becomes sticky during the rainy season due to the deliquescence process.

Deliquescence process:

• It is a process by which a substance absorbs moisture from the atmosphere until it dissolves in the absorbed water and forms a solution.

So, the common salt generally contains a small percentage of Magnesium chloride (MgCl₂) which is of deliquescent nature. When exposed to the atmosphere, it becomes moist and becomes sticky.
