20 mL of 0.244 M hypochlorous acid (HClO) has been titrated with 0.150 M of sodium hydroxide. How can I find pH?
The Ka of the solution is 3.0 * 10^-8.
How do I calculate the pH of the solution once 10mL of the 0.150 M has been added? Which equation should I use in order to find the correct answer? Thanks!

Given,
Consider the equilibrium,
Where
Let's assume that the hydroxide ions will consume one equivalent of hypochlorous acid protons.
Now, recall,
where,
Hence,
at this point in the titration curve.
