Calculate the Ka for the unknown acid in flask. Based on the pH when the acid is 1/4, 1/2, 3/4 neutralized. Acid is being titrated with NaOH from Buret.

1. Concentration of unknown acid .1 m Concentration of base NaOH .1 mPH when 1/4 neutralized is 5.22.
2. Volume NaOH added when acid is 1/4 neutralized 20ml.PH when 1/2 neutralized 5.51.
3. Volume NaOH 1/2 neutralized 22.5mlPH when 3/4 neutralized 6.03.
4. Volume NaOH 3/4 neutralized 24.5ml
