Give an example of a salt that can decrease the ionization of HClO2 (aq). Give an example of a salt that can decrease the ionization of NH3 (aq).

Question

a) Give an example of a salt that can decrease the ionization of HClO_{2 (aq)}.

b) Give an example of a salt that can decrease the ionization of NH_{3 (aq)}.

Answer 1

a). HClO₂(aq) <==> H+ + ClO₂(q)

A salt that will decrease the ionization of HClO₂ would be NaClO₂

b). NH₃ + H₂O <==> NH₄OH

A salt that will decrease "the ionization" of NH₃ would be NH₄Cl

These answers are based on LeChatelier's principle where if you add or increase the concentration of product, the reaction will shift to the left toward the reactant side. In these cases, that will decrease the ionization.
