Ammonium hydroxide ionizes as follows: nh4oh(s) nh4 +(aq) + oh-(aq). if an excess of ammonium salt, such as nh4cl (which ionizes to give nh4 +(aq) ions) is added to the equilibrium shown above, you could predict that the result will be

Concentration of OH- ions will be lowered

Explanation:

NH4OH is a weak electrolyte whereas NH4Cl is a strong electrolyte. The ionization can be depicted as follows:

NH4OH ↔ NH4+ + OH-

NH4Cl → NH4+ + Cl-

Addition of NH4Cl to NH4OH introduces a common ion i.e. NH4+.

The presence of a common ion supplied by a strong electrolyte will suppress the ionization of the weak electrolyte, this is called common ion effect.

In this case, the ionization of NH4OH will be suppressed which will lower the concentration of OH- ions.
