The spectator ions in the precipitation equation Pb(NO₃)₂+ 2KI → PbI₂ + 2KNO₃are ________.

Question

Quizplus · Accepted Answer

In the given precipitation equation, Pb(NO₃)₂ and 2KI are the reactants. The products are PbI₂ and 2KNO₃. During the reaction, the lead and iodine ions combine to form the insoluble precipitate PbI2. The remaining ions in the reactants and products, K+ and NO₃, are called spectator ions as they do not actually participate in the reaction and remain in their ionic form. Hence, the spectator ions in the given precipitation equation are K⁺ and NO₃^-, which corresponds to choice B.
