The half‑equivalence point of a titration occurs half way to the equivalence point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted. If 0.480 moles of a monoprotic weak acid ( K a = 5.9 × 10 − 5 ) is titrated with NaOH , what is the pH of the solution at the half‑equivalence point?
