Chapter 15, Problem 56AE

(a)

Interpretation Introduction

Interpretation:

The temperature when $\text{pH}$ is greater has to be found.

Concept Introduction:

The acidity strength is quantified by the magnitude of a parameter called $\text{pH}$. The strong acids tend to lower values of $\text{pH}$. 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.

(b)

Interpretation Introduction

Interpretation:

The temperature when concentration of ${\text{H}}^{+}$ ions is higher has to be found.

Concept Introduction:

Refer to part (a).

(b)

Interpretation Introduction

Interpretation:

The temperature when water is neutral has to be found.
