See under COPPER AND ITS SALTS Lead Dichromate, PbCr207, mw 423.23 brick red or brn-red,amorph or cryst pdr mp( ) decomp by w sol in ale or alkalies(Ref 5) can be prepd by treating Pb chromate with a coned soln of chromic acid or by other methods (Ref 1). It is a powerful oxidizer and reacts vigorously when heated with reducing materials when heated to decompn, it emits highly toxic fumes of lead(Ref 4) can probably be used for the same purposes as PbCr04, namely in pyrotechnics... [Pg.66]

Lead Dichromate, PbCr.20, containing 2 molecules of water of crystallisation, was described by Preis and Rayman, but its existence was subsequently denied. When a very concentrated solution of chromic acid (130 grams CrOg per 100 c.c.) is electrolysed with a lead anode, a solution is obtained which evolves oxygen when kept, and deposits reddish-brown needles of lead dichromate, PbCr O,. From the volume of oxygen evolved it appears that plumbic dichromate is formed and decomposes thus ... [Pg.55]
