Verified step by step guidance1
Identify the cations present in the solution: Lead (IV) (Pb^4+) and Cesium (Cs^+).
Consider the solubility rules for common ionic compounds to determine which reagent can selectively precipitate one of the cations.
Lead (IV) ions can form insoluble sulfides, such as PbS, when reacted with sulfide ions (S^2-).
Evaluate the reagents provided: K2S contains sulfide ions (S^2-) which can react with Pb^4+ to form an insoluble precipitate of PbS, effectively separating it from Cs^+.
Conclude that K2S is the appropriate reagent to separate the cations by forming a precipitate with Lead (IV) ions, while Cesium ions remain in solution.
