Description
Lead (II) iodide (chemical formula: PbI) is a kind of inorganic
salt. It appears as a bright yellow crystalline solid. It has some
special applications such as the manufacture of solar cells, X-rays,
and gamma-ray detectors. In addition, it can also be used as a paint
pigment for being used in art for bronzing and in gold-like mosaic
tiles. It can be commonly synthesized through a double displacement
reaction between potassium iodide KI and lead (II) nitrate Pb(NO3)2
in water solution. Lead (II) acetate and sodium iodide can also be
used as the substitute of lead nitrate and potassium iodide,
respectively. Alternatively, it can be manufactured through the
reaction between iodine vapor and the molten lead. It is also used
in printing and photography. However, it is hazard to the
environment, and should be taken care of to limit spread to the
environment.
