Question 1

Carbonic acid is a diprotic acid, H2CO3, with Ka1 = 4.2 10–7 and Ka2 = 4.8 10–11 at 25ºC. The ion product for water is Kw = 1.0 10–14 at 25ºC. What is the OH– concentration of a solution that is 0.18 M in Na2CO3?

◦ 6.1 10–3M
◦ 2.1 10–4M
◦ 6.5 10–5M
◦ 2.9 10–6M
◦ 2.7 10–4M

Question 2

Consider a solution made by mixing HCN (Ka= 6.2 × 10–10) with HC2H3O2(Ka= 1.8 × 10–5) in aqueous solution. What are the major species in solution?

◦ H+, CN–, H+, C2H3O2–, H2O
◦ HCN, H+, C2H3O2–, H2O
◦ H+, CN–, HC2H3O2, H2O
◦ H+, CN–, H+, C2H3O2–, OH–, H2O
◦ HCN, HC2H3O2, H2O
