Question 1

How many moles of Fe(OH)2 [Ksp = 1.8 × 10–15] will dissolve in 1.0 liter of water buffered at pH = 10.32?

◦ 4.1 × 10–8
◦ 2.1 × 10–4
◦ 4.4 × 10–8
◦ 2.4 × 107
◦ 8.6 × 10–12

Question 2

If 30 mL of 5.0 × 10–4M Ca(NO3)2 are added to 70 mL of 2.0 × 10–4M NaF, will a precipitate occur? (Ksp of CaF2 = 4.0 × 10–11)

◦ No, because the ion product is greater than Ksp.
◦ Yes, because the ion product is less than Ksp.
◦ No, because the ion product is less than Ksp.
◦ Not enough information is given.
◦ Yes, because the ion product is greater than Ksp.
