Ammonia, NH3, is a weak base with a Kb value of 1.8×10−5.
Part A
What is the pH of a 0.370 M ammonia solution?
Part B
What is the percent ionization of ammonia at this concentration?
A weak base will not dissolve completely. A weak base may have unionized molecules as well as ions. Ionization is typically a reactant which is evident by the lower steady state value. More reactants are found in comparison to equilibrium products.
