Question 1

From the following chemical reactions determine the relative Br∅nsted-Lowry base strengths (strongest to weakest).

2 NaH(s) + H2O(l) → 2 NaOH + H2(g)
NH3(aq) + H2O(l) ⇌ NH4+(aq) + OH-(aq)

◦ OH-> H- > NH3
◦ H- > OH- > NH3
◦ H- > NH3 > OH-
◦ OH- > NH3 > H-

Question 2

The equilibrium constant, K, for the reaction shown below has a value 1.8 × 10-5. In this reaction which is the strongest acid and which is the strongest base?

CH3CO2H(aq) + H2O(l) ⇌ H3O+(aq) + CH3CO2-(aq)

◦ H3O+ and H2O
◦ H3O+ and CH3CO2-
◦ CH3CO2H and H2O
◦ CH3CO2H and CH3CO2-
