Chapter 17, Problem 70E

(a)

Interpretation Introduction

To determine: The possibility for the precipitation of $\text{Co}{\left(\text{OH}\right)}_{\text{2}}$ if the $\text{pH}$ of $0.020\text{M}$ solution of $\text{Co}{\left({\text{NO}}_3\right)}_{\text{2}}$ is adjusted to $8.5$ .

(b)

Interpretation Introduction

To determine: The possibility for the precipitation of ${\text{AgIO}}_3$ when $20\text{mL}$ of $0.010\text{M}$

${\text{AgIO}}_3$ is mixed with $10\text{mL}$ of $0.015\text{M}$ solution of ${\text{NaIO}}_3$ .
