Chapter 9, Problem 9.108E

Predict the relative pH (greater than $7$, less than $7$, etc.) for water solutions of the following salts. Table $9.9$ may be useful. For each solution in which the pH is greater or less than $7$, explain why and write a net ionic equation to justify your answer.

a. Sodium hypochlorite, $\text{NaOCl}$ ( $\text{HOCl}$ is a weak acid)

b. Sodium formate, ${\text{NaCHO}}_2$

c. Potassium nitrate, ${\text{KNO}}_{\text{3}}$

d. Sodium phosphate, ${\text{Na}}_3{\text{PO}}_{\text{4}}$
