Tarnished lead (left) and shiny lead (right) Compounds of lead exist with lead in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions. [1] Red α-PbO and yellow β-PbO The mixed valence oxide Pb 3 O 4 Black PbO 2 which is a strong ...
Lead(II) chromate can be produced by treating sodium chromate with lead salts such as lead(II) nitrate or by combining lead(II) oxide with chromic acid.. Related lead sulfochromate pigments are produced by the replacement of some chromate by sulfate, resulting in a mixed lead-chromate-sulfate compositions Pb(CrO 4) 1−x (SO 4) x.
The lead-containing pigment chrome yellow was used for a very long time before environmental regulations discouraged its use. [7] When used as oxidizing agents or titrants in a redox chemical reaction , chromates and dichromates convert into trivalent chromium, Cr 3+ , salts of which typically have a distinctively different blue-green color.

Lead paint or lead-based paint is paint containing lead. As pigment, lead(II) chromate (Pb Cr O 4, "chrome yellow"), lead(II,IV) oxide, (Pb 3 O 4, "red lead"), and lead(II) carbonate (PbCO 3, "white lead") are the most common forms. [1] Lead is added to paint to accelerate drying, increase durability, maintain a fresh
