2- Weak acid - Strong base titration :- eg. CH 3 COOH (pKa = 4.74) and NaOH

2- Weak acid - Strong base titration :- eg. CH 3 COOH (pKa = 4.74) and NaOH We have sample of 100 ml 0.1 N HAc and tirate against 0.1 N NaOH Before the titration pH is due to the sample i.e. HAc (weak acid) therfore pH = 1/2pKa + 1/2 pCa = 2.37 + 0.5 = 2.87
