Nigeri Sapling Learning ???? 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 0.420 moles of a monoprotic weak acid (Ka solution at the half-equivalence point? 7.9 105) is titrated with NaOH, what is the pH of the Number 4F5F6F7F8F9F10F11F12PrtScP

Explanation / Answer

Ka   = 7.9*10^-5

PKa   = -logKa

          = -log7.9*10^-5

         = 4.1

PH   = PKa + log[salt]/[Acid]

at half equalent point [salt] = [acid]

PH   = PKa + log1

PH   = Pka

PH   = 4.1 >>>>>answer
