Question

Unsaturated solution

• A. can dissolve more solute.
• B. cannot dissolve any more solute.
• C. is not homogeneous.
• D. becomes saturated on standing.

Answer 1

The correct option is A

can dissolve more solute.

• A solution which contains the maximum amount of solute that can be dissolved in the solvent at a given temperature is called saturated solution.
• The amount of the solute in saturated solution at this temperature is called solubility.
• In other words no more salt can be dissolved in a saturated solution at a given temperature.

Explanation for the correct answer, option (a),

• The solution containing lesser amount of solute than the saturated solution at a given temperature is called an unsaturated solution.
• The solvent has the capacity of dissolving any more amount of solute under the given solution.
• Therefore an Unsaturated solution can dissolve more solute.

Explanation for incorrect answer

• (b) A saturated solution cannot dissolve any more salt but an unsaturated solution can dissolve more salt.
• (c) Saturated and unsaturated solutions are homogeneous.
• ( d) The saturated and unsaturated solutions have uniform composition and the particles are uniformly mixed.The particles never settle down on standing.

Hence, option (a) is correct.
