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 0.200 moles of a monoprotic weak acid (?a=5.4×10−5) is titrated with NaOH, what is the pH of the solution at the half‑equivalence point?
