When lead nitrate reacts with potassium iodide then a yellow precipitate of Lead Iodide (PbI2) is formed. The chemical compound potassium iodide is also used as a supplement, medication, and food. It is a drug used to treat hyperthyroidism, to protect the thyroid gland during radiation emergencies, and when specific radiopharmaceuticals are used.

Reaction of Lead Nitrate with Potassium Iodide
A precipitation and double displacement reaction occurs when lead nitrate and potassium iodide are combined. The reaction between lead nitrate (Pb(NO3)2) and potassium iodide (Kl) results in an ion exchange that produces potassium nitrate (KNO3) and a yellow precipitate of lead iodide (PbI2).
Precipitation Reaction
When cations and anions in an aqueous solution react to form a precipitate, an insoluble ionic solid, precipitation reactions take place. The solubility rules for common ionic solids can be used to determine whether or not such a reaction takes place.
Double Displacement Reaction
A type of chemical reaction known as a double displacement reaction sees the reactant ions swap positions to create new products. Precipitate formation frequently follows a double displacement reaction. Covalent or ionic bonds may be present in the chemical reactions between the reactants.
Summary:
When Lead Nitrate reacts with Potassium Iodide then a Yellow Precipitate of?
A yellow precipitate of Lead Iodide (PbI2) is formed when lead nitrate reacts with potassium iodide. When lead nitrate and potassium iodide react with each other, a precipitation and double displacement reaction take place.
