but lead sulfate is more soluble than lead carbonate, which is in turn more soluble than lead phosphate
. (The oxidation state of an element is a rough measure of how many electrons it has lost to other, nearby elements that are attracting the electrons more strongly.)
The building was stocked with powdered lead phosphate
dibasis, used to make PVC, and a respiratory and skin irritant.
In some halogenated polymers, such as chlorinated polyethylene (CPE), chlorosulfonated polyethylene (CSM), polychloroprene (CR) and epichlorohydrin (ECO), additives such as litharge, red lead, dibasic lead phthalate and dibasic lead phosphate
are used to scavenge HCI produced in crosslinking, as well as from degradation during processing (ref.
