Question 11

When sodium chloride is added to a definite volume of water and stirred well, a solution is formed, but there is no increase in the level of water. Why?

Answer

There are some intermolecular spaces between the particles of water. When sodium chloride is added into water and stirred, the particles of sodium chloride occupy the intermolecular spaces present in water particles and gets accommodated so there is no increase in the level of water.
