Question

Write the net ionic equations for the following neutralization, precipitation and

complexation reactions. If no reaction occurs, write

no rxn

.

a. mixing a solution of ammonia with solid silver chloride (solid dissolves).

b. mixing a solution of hypochlorous acid (HOCl) with a solution of sodium hydroxide.

c. mixing a solution of cadmium (II) nitrate with excess 6 M ammonia.

d. mixing solution of dilute hydrochloric acid with a solid bismuth (III) hydroxide (solid dissolves).

Answer 1

a.)  AgCl(s) + 2 NH3(aq) --> [Ag(NH3)2]+(aq) + Cl–(aq)

b.)  HOCl(aq) + OH−(aq) → OCl−(aq) + H2O(l)

c.) Cd²⁺(aq) + 2NH₃(aq) + 2H₂O(l) ---> [Cd(NH₃)₄]²⁺(aq) + 2OH^-(aq) + 2NH₄⁺(aq)

d.) Bi(OH)₃(s) + 3H⁺(aq) <==> Bi³⁺(aq) + 3H₂O(l)
