Question 1

A 100.-mL sample of solution contains 10.0 mmol of Ca2+ ion. How many mmol of solid Na2SO4 must be added in order to cause precipitation of 99.9% of the calcium as CaSO4? The Ksp of CaSO4 is 6.1 × 10–5. Assume the volume remains constant.

◦ 17.4
◦ 10.0
◦ 61.0
◦ 71.0
◦ 6.1

Question 2

A 300.0-mL saturated solution of copper(II) peroidate, Cu(IO4)2, contains 0.31 grams of dissolved salt. Determine the value of Ksp.

◦ 1.1 × 10–5
◦ 2.2 × 10–5
◦ 2.3 × 10–3
◦ 5.0 × 10–8
◦ 1.3 × 10–9
