Chapter 15, Problem 61AE

Interpretation Introduction

Interpretation:

The new molarity when $\text{10}\text{.0 mL}$ of $12\text{ M HCl}$ is diluted by addition of $250.0\text{ mL}$ water has to be calculated.

Concept Introduction:

The dilution formula is given as follows:

  $M_1{V}_1=M_2{V}_2$

Here,

$M_1$ denotes molarity of  initial solution before dilution.

$V_1$ denotes the volume before dilution.

$M_2$ denotes molarity of final solution after dilution.

$V_2$ denotes volume after dilution.

The expression to evaluate $\text{pH}$ is as follows:

  $\text{pH}=-\log \left[{\text{H}}^{+}\right]$

Here,

$\left[{\text{H}}^{+}\right]$ denotes concentration of ${\text{H}}^{+}$ ions.
