Expert Answer
1)Both the reactants KI and Pb(NO3)2 are colorless solutions.
When these solutions are poured together, a yellow colour lead iodide is the product formed which precipitates out of the solution.
2) Lead iodide(PbI) is yellow in colour which precipitates out.
3)2KI(aq) + Pb(NO3)2(aq) →2KNO3(aq) + PbI(s)
