Chapter 17, Problem 15E

(a)

Interpretation Introduction

To calculate: The $\text{pH}$ of a solution that is $0.060\text{M}$ in potassium propionate $\left({\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{COOK}\right)$ and $0.085\text{M}$ in propionic acid $\left({\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\text{COOH}\right)$ .

(b)

Interpretation Introduction

To calculate: The $\text{pH}$ of a solution that is $0.075\text{M}$ in trimethylamine $\left({\left({\text{CH}}_3\right)}_3\text{N}\right)$ and $0.10\text{M}$ in trimethylammmonium chloride $\left({\left({\text{CH}}_3\right)}_3\text{NHCl}\right)$ .

(c)

Interpretation Introduction

To calculate: The $\text{pH}$ of a solution that is made by mixing $50.0\text{mL}$ of $0.15\text{M}$ acetic acid $\left({\text{CH}}_3\text{COOH}\right)$ and $50\text{mL}$ of $0.20\text{M}$ in sodium acetate $\left({\text{CH}}_3\text{COONa}\right)$ .
