Chapter 5, Problem 5.24P

Interpretation Introduction

Interpretation:

The $pH$ for hydrochloric acid of given concentration has to be estimated.

Concept Introduction:

Strong Acids: Acids that dissociates into ions completely which results in easy donation of protons are considered as strong acids. Strong acid forms weaker conjugated base.

$\text{pH}$: The concentration of hydrogen ion is measured using $\text{pH}$ scale. The $\text{pH}$ of a solution is a figure that expresses the acidity or the alkalinity of a given solution.

It is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.

$\text{pH}\text{=}{\text{-log[H}}_{\text{3}}{\text{O}}^{\text{+}}\text{]}$

The activity are used to express thermodynamic properties of solutes. Activities $\left(a_J\right)$ are given by multiplication of molar concentration $\left(c_J\right)$ and activity coefficient $\left({\gamma }_J\right)$.
