Question: A diprotic acid has a pKa1 = 2.90 and pka2 = 6.50. What is the pH of a 0.10 M solution of this a... A diprotic acid has a pKa1 = 2.90 and pka2 = 6.50. What is the pH of a 0.10 M solution of this acid that has been one quarter neutralized? also its not as easy using one of the pka values, another person said it was pH was 2.42 and that's wrong.
Here if you consider second dissociation then also answea will not be affected as there is large difference in the two Ka values.
