Question 1

A solution is prepared by adding excess PbI2(Ksp= 1.42 × 10–8) to water. What is the [I–] at equilibrium?

◦ 1.53 × 10–3 mol/L
◦ 7.10 × 10–9 mol/L
◦ 1.19 × 10–4 mol/L
◦ 8.95 × 10–26 mol/L
◦ 3.05 × 10–3 mol/L

Question 2

A solution is prepared from 3.5 × 102mL of 3.2 M Pb(NO3)2 and 2.0×102 mL of 0.020 M NaCl. Given that Ksp for lead chloride is 1.6×10-5, will precipitation occur?
