Less common lead oxides are: 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(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O. PbO occurs in two polymorphs : litharge having a tetragonal crystal structure , and massicot having an orthorhombic crystal structure .
Nitric acid dissolves the lead(II) oxide component, leaving behind the insoluble lead(IV) oxide: Pb 3 O 4 + 4 HNO 3 → PbO 2 + 2 Pb(NO 3) 2 + 2 H 2 O. With iron oxides and with elemental iron, lead(II,IV) oxide forms insoluble iron(II) and iron(III) plumbates, which is the basis of the anticorrosive properties of lead-based paints applied to ...
Metallic lead is attacked (oxidized) only superficially by air, forming a thin layer of lead oxide that protects it from further oxidation. The metal is not attacked by sulfuric or hydrochloric acids. It dissolves in nitric acid with the evolution of nitric oxide gas to form dissolved Pb(NO 3) 2. 3 Pb + 8 H + + 8 NO − 3 → 3 Pb 2+ + 6 NO − ...
Lead(II) oxide gives a mixed oxide on further oxidation, Pb 3 O 4. It is described as lead(II,IV) oxide, or structurally 2PbO·PbO 2, and is the best-known mixed valence lead compound. Lead dioxide is a strong oxidizing agent, capable of oxidizing hydrochloric acid to chlorine gas. [77]
This method will also work with lead(II) carbonate or lead(II) oxide. Pb + H 2 O 2 + 2 H + → Pb 2+ + 2 H 2 O Pb 2+ + 2 AcO − → Pb(OAc) 2. Lead(II) acetate can also be made by dissolving lead(II) oxide in acetic acid: [7] PbO + 2 AcOH → Pb(OAc) 2 + H 2 O. Lead(II) acetate can also be made via a single-displacement reaction between copper ...
About 60% of the weight of an automotive-type lead–acid battery rated around 60 A·h is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. [8] For example, there are approximately 8.7 kilograms (19 lb) of lead in a typical 14.5-kilogram (32 lb) battery.
