Question

41. (a) What is a saturated solution ? Explain with an example,
(b) What will happen if the saturated solution of a substance in water is (i) heated, and (in) cooled?
​

Answer 1

1. Ans: A solution that can not dissolve a further amount of solute at a particular temperature is called a saturated solution. For example, when you keep adding sugar to the water, time will reach when no more sugar will dissolve in the water and sugar will settle down at the bottom.
2. If the saturated solution of a substance at a particular temperature is cooled to a lower temperature, then the solubility of the substance decreases and some of the dissolved substance will separate out in form of solid crystals. Hot water will dissolve more substance whereas cold water will dissolve less substance.

Answer 2

a)No more solute can be added is called saturated solution

example: No more salt can be added in the water this situation is called saturated solution
