Chapter 16, Problem 16.106QP

Interpretation Introduction

Interpretation: The $\text{pH}$ at $\text{25}{}^{\text{o}}\text{C}$ of a solution that results from mixing together equal volumes of a $0.\text{05}\text{M}$ solution of acetic acid and a $\text{0}\text{.025}\text{M}$ solution of sodium hydroxide is to be calculated.

Concept introduction: The $\text{pH}$ of the solution is calculated by Henderson-Hasselbalch equation,

$\text{pH}=\text{p}{K}_{\text{a}}+\text{log}\frac{\left[\text{Base}\right]}{\left[\text{Acid}\right]}$

To determine: The $\text{pH}$ at $\text{25}{}^{\text{o}}\text{C}$ of a solution that results from mixing together equal volumes of a $0.\text{05}\text{M}$ solution of acetic acid and a $\text{0}\text{.025}\text{M}$ solution of sodium hydroxide.
