Consider the equation. NaCl ( aq ) + AgNO 3 ( aq ) ⟶ AgCl ( s ) + NaNO 3 ( aq )

Question

Identify the spectator ions in the equation.

NO-3(aq)

Na+(aq)

Cl-(aq)

Ag+(aq)

Answer 1

NaCl(aq) + AgNO₃(aq) ==> AgCl(s) + NaNO3(aq)

The only insoluble product is AgCl, so Ag⁺ and Cl^- ions take part in the reaction. The others are spectators.

Ag⁺(aq) + Cl^-(aq) ==> AgCl(s) ... net ionic equation

Spectators are Na⁺ and NO₃^- ions.
