NH4Cl → protonated amine → weak acid
NH3 → weak base
Reaction will appear as:
Part A: If solutions of NH4Cl(aq) and NH3(aq) are mixed, which ions in the resulting solution are spectator ions in any acid-base chemistry occurring in the solution?
Part B: What equilibrium reaction determines [OH−] and, therefore, the pH of the solution? Express your answer as a chemical equation. Identify all of the phases in your answer.
