Break up all the aq compounds into its ions this is TOTAL3. In the complete ionic equation soluble ionic compounds and strong acids are rewritten as dissociated ions. Then write the ionic equation showing all aqueous substances as ions.
Cancel out spectator ions.
There are three steps to writing a net ionic equation. Write a balanced net ionic equation for this reaction. The net ionic equation is Br aq Ag aq AgBr s In the second equation the Mg 2 aq and NO 3 aq ions are spectator ions so they are canceled. A net ionic equation is derived from a balanced chemical equation so we need to.
