The diprotic acid H2A has Ka1 = 5.6 x 10-6 and Ka2 = 3.9 x 10-10. Calculate the pH of a 0.045 M solution of H2A.Insert your answer in decimal notation rounded to 2 decimal digits (i.e. to the hundredths place).

Calculate the pH of the solution.  Assume 1.0 L of solution. You must identify the type of solution before calculating the pH. Express all pH values to two decimal places.   0.180 moles NaOH and 0.400 moles HC2H3O2 Ka (HC2H3O2) = 1.8 x 10-5
