Ionic equation
What is Ionic equation?
An ionic equation shows only the species that actually change during a reaction: aqueous ionic compounds are written as separate ions, unchanged spectator ions are cancelled, and the equation must balance for atoms and for total charge.
This definition is part of the Stoichiometry chapter in Cambridge O Level Chemistry.
