Verified step by step guidance1
Understand the types of chemical equations: A molecular equation shows the complete chemical formulas of reactants and products without indicating their ionic nature. A complete ionic equation breaks down all soluble ionic compounds into their respective ions. A net ionic equation only includes the ions and molecules directly involved in the reaction, excluding spectator ions.
Identify spectator ions: Spectator ions are ions that do not participate in the actual chemical reaction and remain unchanged on both sides of the equation.
Analyze the molecular equation: In a molecular equation, compounds are represented as molecules, so spectator ions are not explicitly shown.
Examine the complete ionic equation: In a complete ionic equation, all soluble ionic compounds are dissociated into ions, including spectator ions, which are shown but do not participate in the reaction.
Consider the net ionic equation: In a net ionic equation, only the ions and molecules that participate in the reaction are included, so spectator ions are omitted.
