Question

which ions remain in solution after pbl2 precipitation is complete? express your answers as ions separated by a comma.

Explanation:

Step1: Consider a typical reaction forming PbI₂

Assume a reaction like Pb(NO₃)₂ + 2KI → PbI₂↓+ 2KNO₃.

Step2: Identify non - precipitating ions

In this reaction, K⁺ and NO₃⁻ do not participate in the precipitation of PbI₂. They remain in solution as spectator ions.

Answer:

K⁺,NO₃⁻
