Chapter 13, Problem 20QRT

(a)

Interpretation Introduction

Interpretation:

The given $\text{25}\text{.0 g}{\text{NH}}_{\text{4}}\text{Cl }\left(s\right)$ dissolved in $\text{50}\text{.0 g}{\text{H}}_2\text{O at}{25}^{\text{o}}\text{C}$ whether belong to unsaturated, saturated or super saturated solution.

Concept Introduction:

Saturated solution is the solution that contains maximum quantity of solute dissolved in the solvent. In the given volume of saturated solution amount of solute dissolved in the solvent called solubility. Unsaturated solution is the solution that contains less quantity of solute than saturated solution. Supersaturated solution contains more solute than solute present in the saturated solution.

(b)

Interpretation Introduction

Interpretation:

The given $\text{25}\text{.0 g}{\text{NH}}_{\text{4}}\text{Cl }\left(s\right)$ dissolved in $\text{75}\text{.0 g}{\text{H}}_2\text{O at}{25}^{\text{o}}\text{C}$ is whether belong to unsaturated, saturated or super saturated solution.
