Chemistry

Weak diprotic acid H2A is titrated with 0.2000 MNaOH. The initial concentration of H2A is 0.1000 M andthe initial volume is 50.00 mL.     Ka1 = 1.0 x 10−5      Ka2 = 1.0 x 10−9

(a) (0.2 pt) Identify the predominate species at the firstequivalence point, by chemical formula:

(b) (0.5 pts) Calculate the pH of the acid solution before anybase is added.

(c) (0.5 pts) Calculate the pH at the first equivalencepoint.

(d) (0.2 pts) How many mL base, total, must be added to achievethe 2nd equivalence point?

(e) (0.5 pts) Calculate the pH at the second equivalencepoint.
