Question

Write the balanced molecular and net ionic equations for each of the following neutralization reactions.

(a) Aqueous acetic acid (HC2H3O2) is neutralized by aqueous barium hydroxide.

(b) Solid chromium(III) hydroxide reacts with nitrous acid.

(c) Aqueous nitric acid and aqueous ammonia react.

Answer 1

The balanced molecular and net ionic equations for each of the following neutralization reactions are:

(a) Aqueous acetic acid (HC2H3O2) is neutralized by aqueous barium hydroxide.
2HC2H3O2 + Ba(OH)2 -> Ba(CH3COO)2 + 2H2O

(b) Solid chromium(III) hydroxide reacts with nitrous acid.
Cr(OH)3 + 3HNO2 -> Cr(NO2)3 + 3H2O

(c) Aqueous nitric acid and aqueous ammonia react.
HNO3 + NH3 -> NH4+ + NO3-
