Question 1

Calculate the concentration of oxalate ion (C2O42–) in a 0.175 M solution of oxalic acid (C2H2O4). [For oxalic acid, Ka1 = 6.5 × 10–2, Ka2 = 6.1 × 10–5.]
◦ 0.11 M
◦ 6.1 × 10–5 M
◦ 4.0 × 10–6 M
◦ 0.0791 M
◦ 0.175 M

Question 2

Calculate the H+ ion concentration in a 8.8 × 10–4 M Ca(OH)2 solution.
◦ 8.8 × 10–4  M
◦ 1.8 × 10–3  M
◦ 2.2 × 10–11  M
◦ 1.1 × 10–11  M
◦ 5.7 × 10–12 M
