Question 1

What is the second stepwise equilibrium constant expression for phosphoric acid H3PO4?
◦ Ka2 = ([H3O+]2[HPO42-])/([H3PO4])
◦ Ka2 = ([H3O+][HPO42-])/([H2PO4-])
◦ Ka2 = ([H3O+][H2PO4-])/([H3PO4])
◦ Ka2 = ([H3O+]3[PO43-])/([H3PO4])

Question 2

Calculate the pH of a 0.020 M carbonic acid solution, H2CO3(aq), that has the stepwise dissociation constants Ka1 = 4.3 × 10-7 and Ka2 = 5.6 × 10-11.
◦ 6.37
◦ 1.70
◦ 10.25
◦ 4.03
