Chapter 16.3, Problem 8PE

Interpretation Introduction

Interpretation: The change in $\text{pH}$ when $0.025\text{mole}$ ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\left(aq\right)$ ions is added to $1.00\text{L}$ of the given buffer solutions is to be calculated.

Concept introduction: The potential of ${\text{H}}^{\text{+}}$ ions is called as $\text{pH}$ and the potential of ${\text{OH}}^{-}$ ions is called as $\text{pOH}$. The value of $\text{pH}$ is less than $7$ for acidic solutions and greater than $7$ for basic solutions. For neutral solution the value of $\text{pH}$ is $7$.

To determine: The change in $\text{pH}$ when $0.025\text{mole}$ ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\left(aq\right)$ ions is added to $1.00\text{L}$ of the given buffer solution.
