Practice Net Ionic Equation in Chemistry

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

Quick Recap

A simplified chemical equation that shows only the ions and molecules directly involved in a chemical reaction, with all spectator ions (those unchanged on both.

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.
