Aisi do dhaatu Jin ko Chaku se saralta purvak Kata Ja sakta hai

Answer 1

At the half-equivalence point, pH = pKa when titrating a weak acid. After the equivalence point, the stoichiometric reaction has neutralized all the sample, and the pH depends on how much excess titrant has been added. After equivalence point, any excess strong base KOH determines the pH.
