A solution of weak acid was titrated with base NaOH . The equivalence point was reached when 36.12 ml of have been added. Now, was added to the titrated solution, the pH was found to be 5.0. The of acid is
Answer:
5
Solution:
At equivalence: moles acid = moles base
Added HCl = half of NaOH used → forms buffer (acid = base)
In buffer, pH = pKa
Given pH = 5
Answer: pKa = 5
