Question 1

It is observed that 7.47 mmol of BaF₂will dissolve in 1.0 L of water. What is the value of K_spfor barium fluoride?

◦ 1.1 × 10^–4
◦ 4.2 × 10^–7
◦ 1.7 × 10^–6
◦ 2.2 × 10^–4
◦ 5.6 × 10^–5

Question 2

Silver acetate, AgC₂H₃O_2, is a sparingly soluble salt with K_sp = 1.9 × 10^–3. Consider a saturated solution in equilibrium with the solid salt. Compare the effects on the solubility of adding to the solution either the acid HNO₃ or the base NH₃.

◦ Either substance would decrease the solubility.
◦ NH₃ would increase the solubility, but HNO₃ would decrease it.
◦ NH₃ would increase the solubility, but HNO₃ would have virtually no effect.
◦ Either substance would increase the solubility.
◦ NH₃ would decrease the solubility, but HNO₃ would increase it.
