Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula Pb O. It occurs in two polymorphs : litharge having a tetragonal crystal structure , and massicot having an orthorhombic crystal structure .
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 .
Consider the equation of roasting lead(II) sulfide (PbS) in oxygen (O 2) to produce lead(II) oxide (PbO) and sulfur dioxide (SO 2): 2 PbS + 3 O 2 → 2 PbO + 2 SO 2. To determine the theoretical yield of lead(II) oxide if 200.0 g of lead(II) sulfide and 200.0 g of oxygen are heated in an open container:
Lead(II,IV) oxide is lead(II) orthoplumbate(IV) [Pb 2+] 2 [PbO 4− 4]. [3] It has a tetragonal crystal structure at room temperature, which then transforms to an orthorhombic (Pearson symbol oP28, Space group Pbam, No. 55) form at temperature 170 K (−103 °C). This phase transition only changes the symmetry of the crystal and slightly ...
Tarnished lead (left) and shiny lead (right) Compounds of lead exist with lead in two main oxidation states: +2 and +4. The former is more common. Inorganic lead(IV) compounds are typically strong oxidants or exist only in highly acidic solutions. [1] Red α-PbO and yellow β-PbO The mixed valence oxide Pb 3 O 4 Black PbO 2 which is a strong ...
Nowadays massicot arises during industrial processing of lead and lead oxides, [6] especially in the glass industry, which is the biggest user of PbO. The definition of massicot as orthorhombic PbO dates from the 1840s, [ 5 ] but the substance massicot and the name massicot has been in use since the late medieval era. [ 7 ]
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 ...
