The ions that do not change are called 'spectator ions'.

The ionic equation represents the 'actual' chemical change and omits the spectator ions.

To write a net ionic equation:

Write a balanced molecular equation.

Rewrite the equation showing the ions that form in solution when each soluble electrolyte dissociates into its component ions. Only dissolved strong electrolytes are written in ionic form.

Identify and cancel the spectator ions that occur unchanged on both sides of the equation.

Write correct state symbols.
