Question

Differentiate between a saturated and an unsaturated solution.

How will you test whether a given solution is saturated or not?

Answer 1

Saturated solution	Unsaturated solution
A solution in which no more solute can be dissolved in a definite amount of solvent at a given temperature is called a saturated solution.	A solution in which the solute is in a lesser amount in comparison with the solvent is called an unsaturated solution.
If more solute does not dissolve in the given solution, then it will be a saturated solution.	If more solute gets dissolved, then it will be an unsaturated solution.
For example-$36g$ of Sodium chloride$\left(\mathrm{NaCl}\right)$ dissolved in $100g$ of water at room temperature forms a saturated solution.	Example- Adding $5g,10g$or $20g$ of Sodium chloride $\left(\mathrm{NaCl}\right)$in $100g$ water.

Finding the solution:

1. The solution is said to be unsaturated if more solute dissolves in it. It's because an unsaturated solution has the ability to dissolve more solutes.
2. Additional solutes or crystals do not dissolve in a saturated solution. As a result, even when immersed in a saturated solution, the solute crystal maintains its size.
3. When the liquids are cooled, the saturated solution forms crystals first.
4. Hence we can find out if the solution is saturated or not.
