Question 1

Which of the following reactions are not consistent with the concept of acid base amphoterism?
◦ Al(OH)3(s) ⇌ Al3+(aq) + 3 OH-(aq)
◦ Al(OH)3(s) + OH-(aq) → Al(OH)4-(aq)
◦ Al(OH)3(s) + 3 H3O+(aq) → Al3+(aq) + 6 H2O(l)
◦ H2O(l) + H2O(l) ⇌ H3O+(aq) + OH-(aq)

Question 2

Barium hydroxide is slightly soluble in water, with a Ksp of 5.00 × 10-4 at 298K. The dissolution of barium hydroxide in water is an endothermic process.

Ba+2 (aq) + 2OH- (aq)


Which of the following will increase the solubility?
◦ Sodium hydroxide (NaOH) is added to the solution.
◦ Barium hydroxide is added to the solution.
◦ The temperature is decreased.
◦ HCl is added to the mixture.  (HCl reacts with OH-, removing it from the system.)
