A buffer solution with a volume of 0.0245 L consists of 0.61 M hypochlorous acid (HClO), a weak acid, plus 0.61 M sodium hypochlorite (NaClO). The acid dissociation constant of hypochlorous acid, Ka, is 4.0 ✕ 10−8. Determine the pH of the buffer solution after the addition of 0.0036 mol potassium hydroxide (KOH), a strong base. (Assume no change in solution volume.)
