Lead(ii) iodide or lead iodide is a salt with the formula pbi 2 at room temperature, it is a bright yellow odorless crystalline solid, that becomes orange and red when heated it was formerly called plumbous iodide the compound currently has a few specialized applications, such as the manufacture of solar cells and x-ray and gamma-ray detectors. Lead iodide is toxic due to its lead content lead iodide can be obtained as a yellow precipitate by mixing solutions of lead (ii) nitrate and potassium iodide it is sparingly soluble in cold water but quite soluble in hot water, yielding a colorless solution on cooling it crystallizes as yellow hexagonal platelets. Preparation of salts question qn : the following passage is about the preparation of lead iodide, and insoluble salt an excess of potassium iodide in solution. Determination of the solubility product constant (k sp) of lead (ii) iodide the solubility product constant, k sp, is a particular type of equilibrium constant the. If we want to make an insoluble salt, we can react together two soluble salts in a precipitation reaction making an insoluble salt silver chloride is insoluble - you can see this from the table we need a soluble silver salt and a soluble chloride salt to make it silver nitrate and sodium chloride are both soluble when we mix their solutions.
