Considering the following precipitation reaction: Pb(NO3)2(aq) + 2KI(aq) → PbI2(s) + 2KNO3(aq),
patriot [66]

Answer: The ions which are not spectator ions are Pb^{2+} and I^-

Explanation:

Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.

The given chemical equation is:

Pb^{2+}(aq)+NO_3^-(aq)+2K^+(aq)+2I^-(aq)\rightarrow PbI_2(s)+2K^+(aq)+2NO_3^-(aq)

The ions which are present on both the sides of the equation are K^+ and NO_3^- and are spectator ions.

Thus the net ionic equation is:

Pb^{2+}(aq)+2I^-(aq)\rightarrow PbI_2(s)

Hence, the correct answer is Pb^{2+} and I^-
