It was widely used as a raw material in the manufacturing of pigments for lead paints. The Fe3 + should be completely hydrolyzed to form Fe (OH)3 precipitate to be removed. It is soluble in water and liquid ammonia, being slightly soluble in the ethanol, being insoluble in concentrated nitric acid (produce protective film); it can react with concentrated hydrochloric acid or concentrated alkali chloride solution to form complex chlorinated lead acid or chlorinated lead acid salt; it has strong oxidizing property and may cause the risk of inducing combustion and explosion if mixed with organic matter, reducing agent and combustible substance such as sulfur and phosphorus or even subject to slightly friction. Products that fall under this regulation will be placed on a mandatory 21-day hold after documentation is received. [6][7] It has been produced as a raw material for making pigments such as chrome yellow (lead(II) chromate, PbCrO4) and chrome orange (basic lead(II) chromate, Pb2CrO5) and Naples yellow. When these two solutions are mixed, the lead(II) cations, #"Pb"^(2+)#, and the iodide anions, #"I"^(-)#, will bind to each other and form lead(II) iodide, an insoluble ionic compound.
