The next three (3) problems deal with the titration of 501 mL of 0.501 M carbonic acid (H₂CO3) (Ka1 = 4.3 x 10-7, Ka2 = 5.6 x 10-11) with 1.5 M KOH. What is, the pH of the solution at the 2nd equivalence point? 11.86 vada What will the pH of the solution be when 0.2928 L of 1.5 M KOH are added to the 501 mL of 0.501 M carbonic acid? 10.73
