The bromide and iodide of lead(IV) are not known to exist. [3] Lead dioxide dissolves in alkali hydroxide solutions to form the corresponding plumbates. [2] PbO 2 + 2 OH − + 2 H 2 O → Pb(OH) 2− 6. Lead also has an oxide with mixed +2 and +4 oxidation states, red lead (Pb 3 O 4), also known as minium.

Lead bromide was prevalent in the environment as the result of the use of leaded gasoline. Tetraethyl lead was once widely used to improve the combustion properties of gasoline. To prevent the resulting lead oxides from fouling the engine, gasoline was treated with 1,2-Dibromoethane , which converted lead oxides into the more volatile lead ...

Lead sesquioxide, Pb 2 O 3, which is a lead (II,IV) oxide as well (lead(II) metaplumbate(IV) [Pb 2+][PbO 2− 3]), reddish yellow Pb 12 O 19 , monoclinic, dark-brown or black crystals The so-called black lead oxide , which is a mixture of PbO and fine-powdered Pb metal and used in the production of lead–acid batteries .
Lead(IV) oxide, commonly known as lead dioxide, is an inorganic compound with the chemical formula PbO 2. It is an oxide where lead is in an oxidation state of +4. [ 1 ] It is a dark-brown solid which is insoluble in water. [ 2 ]
Lead (pronounced "led") is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when ...
