Chapter 3, Problem 3.58AP

Interpretation Introduction

(a)

Interpretation:

The reason as to why the concentration of aqueous solution, ${10}^{-3}M$ of either $\text{HI}$ or $\text{HCl}$ in water gives the same $\text{pH}$ reading of $3$ is to be stated.

Concept introduction:

Strong acids dissociate in water completely. They give hydrogen ions. These hydrogen ions combine with water to form hydronium ions. Strong acids conduct electricity due to the presence of free ions.

Interpretation Introduction

(b)

Interpretation:

The reason as to why the solution of the stronger base doesn’t have a higher $\text{pH}$ is to be stated.

Concept introduction:

Strong base dissociates in water completely. They give more hydroxide ions than hydrogen ions. The relation between $\text{pOH}$ and $\text{pH}$ is given by an expression.

$\text{pOH}+\text{pH}=14$
