In the titration of a solution of weak monoprotic acid with a 0. 1525 m solution of naoh, the ph half way to the equivalence point was 4. 48. in the titration of a second solution of the same acid, exactly twice as much of a 0. 1525 m solution of naoh was needed to reach the equivalence point. what was the ph half way to the equivalence point in this titration
