Molecular, Complete and Net Ionic Equations

A molecular equation shows the complete chemical formulas of reactants and products without indicating the ionic nature of the compounds.

A complete ionic equation shows all of the ions present in a solution, including spectator ions.

A net ionic equation shows only the species that participate in the reaction, omitting spectator ions.

Spectator ions are ions that do not participate in the actual chemical reaction and remain unchanged in the solution.

Spectator ions can be identified by comparing the complete ionic equation to the net ionic equation; they are the ions that appear on both sides.

Water often acts as a solvent in ionic reactions, allowing ions to dissociate and interact.

Balancing chemical equations ensures that the law of conservation of mass is upheld, meaning the number of atoms of each element is the same on both sides.

(aq) indicates that a substance is dissolved in water, forming an aqueous solution.

(s) indicates that a substance is in solid form, often as a precipitate in a reaction.

Strong electrolytes completely dissociate into ions in solution, while weak electrolytes partially dissociate.
