Chapter 8, Problem 8.16EP

(a)

Interpretation Introduction

Interpretation:

Heating of salt-water mixture will whether increase or decrease the rate of dissolving a salt in water has to be identified.

Concept Introduction:

Solubility is the quantity of solute (solid, liquid or gas) that will dissolve in a given amount of solvent (solid, liquid or gas) at definite temperature and pressure. Solubility depends on the physical and chemical property of solvent, solute and concentration of the solution.

Three factors which affect the rate of solution formation are given below:

1. 1. The state of subdivision of the solute.
2. 2. The degree of agitation during solution preparation.
3. 3. The temperature of the solution components.

(b)

Interpretation Introduction

Interpretation:

The shaking of the mixture will whether increase or decrease the rate of dissolving a salt in water has to be identified.

Interpretation Introduction

Interpretation:

Heating the table salt prior to adding it to water will whether increase or decrease the rate of dissolving a salt in water has to be identified.
