The half-equivalence point of a titration occurs half way, Ask an Expert

Academics

The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted. If 0.460 moles of a monoprotic weak acid (Ka = 6.3 × 10-5) is titrated with NaOH, what is the pH of the solution at the half-equivalence point?
