Macmillan Leaming An unknown compound, X, is thought to have a carboxyl group with a pKa of 2.5 and a second ionizable group with a pKa between 5.0 and 8.0. When 50.0 mL of 0.2 M NaOH is added to 75.0 mL of a 0.2 M solution of X at pH 2.5, the pH increases to 7.13. Calculate the pKa of the second ionizable group of X. PK, = 6.83 Incorrect
