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. Its prepraration is a popular demonstration in basic chemistry education, to teach topics such as double displacement reactions and stoichometry. It is decomposed by light at moderately high temperatures and this effect has been used in a patented photographic process.
Lead iodide was formerly employed as a yellow pigment in some paints, with the name iodide yellow. However, that use has been largely discontinued due to its toxicity and poor stability.
Its water solubility is 0.044 g/100 mL (0 °C),0.0756 g/100 mL (20 °C),
0.41 g/100 mL (100 °C).
It is insoluble in ethanol, cold HCl ,soluble in alkalis, KI solution, methyl isopropyl ketone.
