Question 1

If you know Kb for ammonia, NH3, you can calculate the equilibrium constant, Ka, for the following reaction:

NH4+ + H2O ⇌ NH3 + H3O+

using the equation:
◦ Ka = 1 / Kb
◦ Ka = Kb / Kw
◦ Ka = Kw / Kb
◦ Ka = Kw × Kb

Question 2

If an equal number of moles of the weak acid HCN and the strong base KOH are added to water, is the resulting solution acidic, basic, or neutral?
◦ basic
◦ neutral
◦ acidic
◦ There is insufficient information provided to answer this question.
