Question:

A hypothetical weak acid, HA, was combined with NaOH in the following proportions: 0.20 mol of HA, 0.080 mol of NaOH. The mixture was diluted to a total volume of 1.0 L and the pH measured.

(a) If pH = 4.80, what is the pK_a of the acid?

(b) How many additional moles of NaOH should be added to the solution to increase the pH to 5.00?
