Question

Considering the following precipitation reaction: Pb(NO₃)₂(aq)+ 2KI(aq)→ PbI₂(s)+ 2KNO₃(aq) What is the correct net ionic equation?

Quizplus · Accepted Answer

The net ionic equation shows only the species that are involved in the reaction, omitting spectator ions (ions that appear on both the reactant and product side, but do not participate in the reaction). In this reaction, the spectator ions are the nitrate ion (NO3-) from the lead nitrate and the potassium ion (K+) from the potassium iodide. Therefore, the net ionic equation is: Pb2+(aq) + 2I-(aq) → PbI2(s)
