Lead (IV) oxide is used to manufacture rubber substitutes. At a temperature of around 1,000C (1,800F) the sulfide is converted to the oxide:[5], There are two principal methods to make lead monoxide both of which resemble combustion of the lead at high temperature:[6]. PbO is used in certain condensation reactions in organic synthesis.[18]. As an intermediate product in the processing of raw lead minerals into a metallic lead, PbO is developed on a large scale. 0000006276 00000 n
Observe that Pb2+ solubility drops 10,000 fold as SO24 reaches 0.1M. The addition of chloride can lower the solubility of lead, though in chloride-rich media (such as aqua regia) the lead can become soluble again as anionic chloro complexes. Chronic poisoning displays as agitation, irritability, vision disorders, hypertension, and a grayish facial hue. American Elements shall not be held liable for any damage resulting from handling or from contact with the above product.
