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 sides) removed.

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