If aqueous solutions of Pb(NO₃)₂ and NaCl are mixed, which ions, if any, are spectator ions? Pb(NO₃)₂(aq) + 2NaCl(aq) → PbCl₂(s) + 2NaNO₃(aq) A) Pb²⁺(aq), Cl^-(aq) B) Na⁺(aq), NO₃^-(aq) C) Pb²⁺(aq), NO₃^-(aq) D) Na⁺(aq), Cl^-(aq) E) None are spectator ions.

Question

Quizplus · Accepted Answer

Spectator ions are ions that do not participate in the chemical reaction and remain in solution unchanged. In this reaction, Na^+ and NO3^- are the spectator ions because they do not form a precipitate or change oxidation state; they remain in the aqueous phase as ions.
