Ammonium nitrate is produced by the reaction of ammonium hydroxide (a weak base) with nitric acid (a strong acid). Kb for ammonium hydroxide is 1.8 x 10-5 according to the following reaction:
NH4OH+H3O+→H2O+NH4 +
Write down the equation for the hydrolysis of NH4 +, the conjugate acid of NH4OH.
What would be the pH of a 0.2 M solution of NH4Cl (the conjugate acid of NH4OH)?
