You create a 1 L solution of 0.1 M H2CO3. carbonic acid, H2CO3,
is a diprotic acid with Ka1 = 4.5 x 10-7 and Ka2 = 4.7 x
10-11.
a) What will the initial pH of the solution be?
b) What volume of 0.1 M NaOH will you need to add to reach the
second equivalence point( remember carbonic acid deprotonates to
bicarbonate HCO3- and then can deprotonate further to CO32-?
c) At the second equivalence point, what will the pH of the
solution be?

In waters affected by acid rain the concentrations of the three carbonic acid species (H2CO3, HCO3-, CO32-) are determined by concentration of the strong acid deposited by acid rain, as well as the concentration of H2CO3 which is controlled by the solubility of carbon dioxide . Under these conditions (constant H2CO3 and relatively low pH) the only carbonic acid equilbrium of importance is the conjugate base reaction of HCO3-, which is related to, but not identical to - and not...
