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 includes only the species that undergo a change during the reaction. The spectator ions (ions that do not change) are not included. In this case, the net ionic equation is Pb(NO₃)₂(aq) + 2I-(aq) → PbI₂(s) + 2NO3-(aq). We can simplify this equation by canceling out the spectator ions (NO3-), leaving only Pb2+(aq) + 2I-(aq) → PbI2(s).
