Lead+Chromate

Lead(II) chromate may also be known as chrome yellow, chromic acid lead(II) salt, canary chrome yellow 40-2250, chrome green, chrome green UC61, chrome green UC74, chrome green UC76, chrome lemon, crocoite, dianichi chrome yellow G, lemon yellow, king's yellow, Leipzig yellow, lemon yellow, Paris yellow, pigment green 15, plumbous chromate, pure lemon chrome L3GS, and various other names. The mineral [|crocoite], occurring as orange-yellow prismatic crystals, is a moderately rare mineral known from the oxidation zones of such Pb ore beds, that were affected by chromate-bearing solutions, coming from the oxidation of primary Cr minerals ([|chromite]) of the nearby (ultra)[|mafic rocks]. Lead(II) chromate can be destroyed by strong [|reducing agents], [|combustibles], and organic materials.
 * Lead(II) chromate** ([|Pb][|Cr][|O4]) is a [|chemical compound], a [|chromate] of [|lead]. It has a vivid yellow color and is practically insoluble in water, and as a result, is used in paints under the name "[|chrome yellow]". It is commonly made in the laboratory by reacting a lead(II) salt (such as [|lead(II) nitrate]) with a chromate or [|dichromate] salt (such as [|potassium chromate] or [|potassium dichromate]) in solution in water, producing a very deep yellow to orange precipitate of lead(II) chromate.

Lead(II) chromate is used in some [|pyrotechnic compositions], especially [|delay compositions], as an [|oxidizer]. Up to the late 1800s it was used to impart a bright yellow color to some types of [|candy].[|[1]] It has also been used in the paint to color school buses.(Chrome Yellow) Previously, its use was wider. Lead(II) chromate and "[|white lead]", or [|lead(II) carbonate], were the most common [|lead-based paint] pigments.
