Explain a carboxyl group with a pka value

Reference no: EM13558505

An unknown compound, H2A, is thought to have a carboxyl group with a pKa value of 3.2 and another ionizable group with a pKa between 4 and 9. When 75mL of 0.1M NaOH was added to 100mL of a 0.1M solution of H2A at pH 3.2, the pH increased to 6.72. calculate the pKa of the second ionizable group of H2A.
