Question

Quizplus · Accepted Answer

Spectator ions do not participate in the chemical reaction. In this reaction, K+ (from KBr) and ClO4- (from Pb(ClO4)2) do not change their oxidation state or form a precipitate, making K+ a spectator ion.

Given That: Pb(ClO3)2 (Aq) + KBr (Aq) → PbBr2 (S)

Given That: Pb(ClO₃)₂ (Aq) + KBr (Aq) → PbBr₂ (S)
