on 1 of 3 Sapling Learning Map The half reacted to form its conjugate, and the other half stll remains unreacted f 0.560 moles of a monoprotic weak acid (K, 6.6x10%) is titrated with NaOH, what is the pH of the solution at the half-equivalence point? point of a titration occurs half way to the end point, where half of the analyte has Number Previous Gvo Up & View Souton @Check Answer ONext Hint 3 MacBook Air F8 F7 F5 F3 F4 F2

Solution

ka   = 6.6*10^-5

Pka = -logKa

         = -log6.6*10^-5

        = 4.1805

at half equalent point [ salt] = [acid]

PH = PKa + log[Salt]/[acid]

PH = Pka

PH   = 4.1805 at half equalent point
