검증된 단계별 안내1
Identify the reactants and products in the given reaction: Sodium chloride (NaCl) and silver nitrate (AgNO₃) are the reactants, while sodium nitrate (NaNO₃) and silver chloride (AgCl) are the products.
Write the balanced molecular equation for the reaction: NaCl(aq) + AgNO₃(aq) → NaNO₃(aq) + AgCl(s).
Separate the aqueous compounds into their respective ions to write the complete ionic equation: Na⁺(aq) + Cl⁻(aq) + Ag⁺(aq) + NO₃⁻(aq) → Na⁺(aq) + NO₃⁻(aq) + AgCl(s).
Identify the spectator ions, which are ions that appear on both sides of the complete ionic equation and do not participate in the reaction. In this case, Na⁺(aq) and NO₃⁻(aq) are spectator ions.
Remove the spectator ions to write the net ionic equation, which includes only the ions and compounds that undergo a chemical change: Ag⁺(aq) + Cl⁻(aq) → AgCl(s).
