To define if the solution is saturated, unsaturated or supersaturated. Concept Introduction: Not all materials are completely soluble in a solvent at a given temperature. If no more solute can be added in aqueous solution, it is said to be saturated solution. If the amount of solvent is slightly less than required for a saturated solution, the solution is said to be unsaturated solution. If the amount of solute added in the solvent is less than required for a saturated solution, then the solution is unsaturated solution.

Question

Chapter 6, Problem 15P

Interpretation Introduction

Interpretation:

To define if the solution is saturated, unsaturated or supersaturated.

Concept Introduction:

Not all materials are completely soluble in a solvent at a given temperature. If no more solute can be added in aqueous solution, it is said to be saturated solution. If the amount of solvent is slightly less than required for a saturated solution, the solution is said to be unsaturated solution. If the amount of solute added in the solvent is less than required for a saturated solution, then the solution is unsaturated solution.
