9.1 Reactions of Ions in Solutions |
Equations for the reactions of ions: - a formula equation is a chemical equation in which all compounds are represented by their chemical formulas - a total ionic equation is a chemical equation in which all highly soluble ionic compounds are written as dissociated ions - to be balanced, a total ionic equation must meet two criterias: - all entitities on one side of the reaction must be accounted for one another - the net electrical charge on. both sides must be the same Net Ionic Equation - is a chemical equation that includes only the entities that react during the equation - is a simplofied version of the total ionic equation created by omitting all spectator ions - spectator ions are ions that are not involved in a chemical reaction |
