Practice Net Ionic Equation in Chemistry

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

An equation showing only the ions and molecules that actually participate in a reaction, with spectator ions removed.

Strip away the bystanders. Some ions just float around doing nothing — the net ionic equation shows only the ones that actually react.

Example 1

easy
Explain the difference between a molecular equation, a complete ionic equation, and a net ionic equation. Use the reaction of \text{NaCl(aq)} + \text{AgNO}_3\text{(aq)} as an example.

Example 2

medium
Write the net ionic equation for the reaction between \text{BaCl}_2\text{(aq)} and \text{Na}_2\text{SO}_4\text{(aq)}.

Example 3

medium
Write the net ionic equation for the neutralization of hydrochloric acid with sodium hydroxide: \text{HCl(aq)} + \text{NaOH(aq)} \rightarrow \text{NaCl(aq)} + \text{H}_2\text{O(l)}.

Example 4

hard
Write the net ionic equation for the reaction: \text{K}_2\text{CO}_3\text{(aq)} + 2\text{HCl(aq)} \rightarrow 2\text{KCl(aq)} + \text{H}_2\text{O(l)} + \text{CO}_2\text{(g)}. Identify all spectator ions.
