Question

Ammonia ionizes as follows in water:
NH3 + H₂O NH4+ + OH-
The Kb for this reaction is 1.8 x 10-5. Calculate the [OH] if the [NH3] is 0.5M originally. The ammonia is a weak base. Weak base equilibria is done very much like weak acids except the equation and equilibrium constant expression contains [OH] instead of [H*], and the constant is Ka instead of Kb. The rest of the process is the same.
