Question 1

What is the concentration of the Cd2+ion in a 0.035 M Cd(NO3)2solution that is also 1.0 M NH3? At this temperature, Kffor Cd(NH3)42+= 1.0 107.

◦ 3.5 10–9M
◦ 6.4 10–9M
◦ 3.5 10–30M
◦ 1.0 10–7M
◦ None of these are correct.

Question 2

What is the maximum concentration of carbonate ions that will precipitate BaCO3 but not MgCO3 from a solution that is 3.5 10–3M each in Mg2+ and Ba2+? For MgCO3, Ksp = 1.0 × 10–15 and for BaCO3, Ksp = 2.6 × 10–9.

◦ 2.9 × 10–13M
◦ 7.4 × 10–7M
◦ 3.2 × 10–8M
◦ 5.1 × 10–5M
◦ None of these are correct; MgCO3will always precipitate before BaCO3.
