Question- The half-equivalence 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 0.400 moles of a monoprotic weak acid (Ka=5.9 *10^-5 M) is titrated with NaOH, what is the pH of the solution at the half -equivalence point?
pH=?
Please take care to reply the question as mark are evenly granted for each point
