Which is the first step in generating a net ionic equation?

• A. Label all states (s, l, g, aq) for each species.
• B. Balance the chemical equation.
• C. Split all aqueous species into their ions.
• D. Cancel spectator ions.

Answer: (B)

Balancing the molecular equation is the first step. It guarantees conservation of mass and the correct stoichiometric relationships for all species involved. After the equation is balanced, you convert soluble species to their ions to form the complete ionic equation, then identify and cancel spectator ions to obtain the net ionic equation. Labeling states isn’t required for this process, and removing spectators comes after writing the ionic form, so you need the balanced equation before you can do that correctly.
