HClO is a weak acid (Ka = 4.0 × 10–8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.059 M in NaClO at 25 °C?

Question

Before going ahead to do the ice diagram, you have to know that you are looking for the pH of a base. To do that, use the Henderson–Hasselbalch equation pOH=pKb+log[product]/[reactant]

However, we have a ka not a kb. To get the Kb use this rule:
$\large Kw=Kb*Ka$

$\large Kb=\frac{Kw}{Ka}$
Where Kw is 10^(-14)

That's solving for the Kb of ClO-
