Chapter 16, Problem 16.3MP

Interpretation Introduction

Interpretation:

The $\text{pH}$ of a $1.0\text{L}$ buffer after the addition of $10.0\text{mL}$ of $1.00\text{M}$

$\text{HCl}$ to the original buffer that contains $0.100\text{mol}$ in ${\text{HC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$ and $0.100\text{mol}$ in ${\text{NaC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$ is to be calculated.

Concept introduction:

A buffer solution is an aqueous solution that contains the mixture of a weak acid and its conjugate base or the mixture of weak base with its conjugate acid. A buffer solution resists the $\text{pH}$ change by neutralizing added amount of acid or base.

To determine:

The $\text{pH}$ of a $1.0\text{mL}$ buffer after the addition of $10.0\text{mL}$ of $1.00\text{M}$

$\text{HCl}$ to the original buffer that contains $0.100\text{mol}$ in ${\text{HC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$ and $0.100\text{mol}$ in ${\text{NaC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$.
