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.

The net ionic equations for each part is written below.

Explanation:

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.  Solids, liquids and gases do not dissociate into its ions.

The chemical equation for the reaction of acetic acid and barium hydroxide is given as:

Ionic form of the above equation follows:

As, barium and acetate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

The chemical equation for the reaction of chromium (III) hydroxide and nitrous acid is given as:

Ionic form of the above equation follows:

As, no spectator ions are present. So, the above equation is the net ionic equation.

The chemical equation for the reaction of nitric acid and aqueous ammonia (ammonium hydroxide) is given as:

Ionic form of the above equation follows:

As, ammonium and nitrate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:
