Net ionic equation

Question

AgNO3(aq)+KCI(aq)=AgCI(s)+KNO3(aq)

Answer 1

Anytime you have a precipitate formed, you can simply write the net ionic equation as the formation of that precipitate. So, for the current problem, the precipitate is silver chloride, AgCl.

Net ionic equation: Ag+(aq) + Cl-(aq) ==> AgCl(s)

Looking at the full explanation, we will first write the molecular equation, followed by the compete ionic equation, and finally, the net ionic equation.

molecular equation: AgNO₃(aq) + KCl(aq) ==> AgCl(s) + KNO₃(aq)

complete ionic eq: Ag⁺(aq) + NO₃^-(aq) + K⁺(aq) + Cl^-(aq) ==> AgCl(s) + K⁺(aq) + NO₃^-(aq)

net ionic equation: Ag⁺(aq) + Cl^-(aq) ==> AgCl(s) (note: K⁺ and NO₃^- are spectator ions)
