Lead(ii) Iodide is a yellow precipitate while silver chloride is white.
Some examples of simple precipitation reactions include mixing silver nitrate with sodium chloride to form silver chloride precipitate, mixing lead nitrate with potassium iodide to form lead iodide precipitate, and mixing barium chloride with sodium sulfate to form barium sulfate precipitate.
Nickel and zinc chloride: Nickel chloride and zinc Chlorine and sodium: Sodium chloride Potassium nitrate and lead iodide: Potassium iodide and lead nitrate
Lead is a metal that forms insoluble lead (II) iodide (PbI2) and lead (II) chloride (PbCl2). Both compounds are sparingly soluble in water and form solid precipitates when these salts are mixed with water.
Lead iodide (PbI4) is a chemical compound composed of lead and iodine with a 1:4 ratio. It is a yellow, solid material that is insoluble in water. Lead iodide is primarily used in organic light-emitting diodes (OLEDs) and photocatalysis.
Silver chloride and lead (II) chloride do not dissolve well in water.

Lead chloride and silver chloride can be separated by adding dilute hydrochloric acid to the mixture, which will dissolve the lead chloride while leaving the silver chloride unaffected. The solution can then be filtered to separate the two compounds. Alternatively, the compounds can be separated by their different solubilities in ammonia solution, where silver chloride dissolves in excess ammonia but lead chloride remains insoluble.
Lead chloride can be separated from a mixture of silver chloride and lead chloride by adding water to the mixture. Silver chloride is insoluble in water, whereas lead chloride is soluble. Upon adding water, the silver chloride will precipitate out, leaving behind the lead chloride in solution.
Four contempory equilibriums are possible:Pb2+ + 2I- --> PbI2(s) with Ks1 = [Pb2+]*[I-]2 = 1.4*10-8Ag+ + Cl- --> AgCl(s) with Ks2 = [Ag+]*[Cl-] = 1.6*10-10Pb2+ + 2Cl- --> PbCl2(s) with Ks3 = [Pb2+]*[Cl-]2 = 1.6*10-5Ag+ + I- --> AgI(s) with Ks4 = [Ag+]*[I-] = 1.5*10-16With some computational analytical math you can solve the four unknown equilibrium concentrations of all ions from those four given equations Ks(1 to 4) . I'm not sure if there is more Ag+ than Pb2+ in solution or just the other way around. I'm not good enough in math, so if you or anyone else succeeds please let me know.
One method to separate lead chloride from a mixture of lead chloride and silver chloride is to dissolve the mixture in water, then add hydrochloric acid to precipitate the lead chloride while keeping the silver chloride in solution. The precipitated lead chloride can then be filtered out. Another method is to use selective precipitation by adding a potassium chromate solution, which will form a yellow precipitate with the lead chloride while leaving the silver chloride in solution.

Take a few drops of both samples and add some lead nitrate. A yellow precipitate indicates lead iodide and it gives the inference that it contains iodide ions, hence the solution of sodium iodide.

Lead (IV) Iodide [PbO2] is black.- Chloe E.
Lead iodide is an ionic compound made up of lead (Pb) cations and iodide (I) anions. It is not a traditional salt like sodium chloride, but it does possess salt-like properties due to its ionic bond. Lead iodide is often used in scientific research and has applications in materials science and electronics.
