Chapter 3, Problem 15E

(a)

Interpretation Introduction

To determine: The $\text{pH}$ of a buffer containing $0.15\text{mol}$ of propionic acid $\left({\text{C}}_2{\text{H}}_5\text{COOH}\right)$ and $0.10\text{mol}$ of sodium propionate $\left({\text{C}}_2{\text{H}}_5\text{COONa}\right)$ in $1.20\text{L}$ of the solution.

(b)

Interpretation Introduction

To determine: The $\text{pH}$ of a buffer containing $0.15\text{mol}$ of propionic acid $\left({\text{C}}_2{\text{H}}_5\text{COOH}\right)$ and $0.10\text{mol}$ of sodium propionate $\left({\text{C}}_2{\text{H}}_5\text{COONa}\right)$ in $1.20\text{L}$ of the solution after the addition of $0.01\text{mol}$ of $\text{NaOH}$ .
