Chapter 5, Problem 56E

Interpretation Introduction

(a)

Interpretation:

The amount of concentrated $\text{HCl}(aq)$ should be determined.

Concept introduction:

By applying $M_1{V}_1=M_2{V}_2$ formula, the volume of concentrated $HCl(aq)$ solution for the preparation of $20.0L$ $0.10M$ $HCl(aq)$ solution could be determined.

$M_1{V}_1=M_2{V}_2$

Where, $M_1$ is the molarity of the concentrated $HCl(aq)$ solution.

$M_2$ is the molarity of the required diluted $HCl(aq)$ solution.

$V_1$ is the volume of the concentrated $HCl(aq)$ solution.

$V_2$ is the volume of the required diluted $HCl(aq)$ solution.

Interpretation Introduction

(b)

Interpretation:

Molarity of $HCl(aq)$ should be determined.

Concept introduction:

Here exact molarity of the concentrated $HCl(aq)$ solution can be determined by applying

$M_1{V}_1=M_2{V}_2$ formula.

Interpretation Introduction

(c)

Interpretation:

The importance of titration needs to be described.

Concept introduction:

In a titration reaction one can determine the exact concentration of acid by the titrating it with known concentration of base or, vice-versa.
