Chapter 16, Problem 33E

Interpretation Introduction

Interpretation:

The addition of the given amount of each substance to the $500\text{mL}$ buffer solution that is $0.100\text{M}$ in ${\text{HNO}}_{\text{2}}$ and $0.150\text{M}$ in ${\text{KNO}}_{\text{2}}$ resulting in exceeding the capacity of the buffer to neutralize it is to be validated.

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

To validate: The addition of the given amount of each substance to the $500\text{mL}$ buffer solution that is $0.100\text{M}$ in ${\text{HNO}}_{\text{2}}$ and $0.150\text{M}$ in ${\text{KNO}}_{\text{2}}$ resulting in exceeding the capacity of the buffer to neutralize it.
