Lead(II,IV) oxide. Commonly called red lead or minium.
The chemical name for red lead is lead tetroxide, which has the chemical formula Pb3O4. It is a bright red or orange crystalline compound often used as a pigment in paints and in some types of batteries.
Upon heating lead(II,IV) oxide (Pb3O4), it decomposes to form lead(II) oxide (PbO) and oxygen gas (O2). The reaction can be represented as: Pb3O4 → 3PbO + O2. This decomposition typically occurs at elevated temperatures, leading to the release of oxygen and the formation of lead(II) oxide.
The formula of red lead, tri-lead tetroxide, is Pb3O4.
The formula for white lead is 2PbCO3 · Pb(OH)2, for red lead it is Pb3O4, and for sugar of lead it is Pb(C2H3O2)2.
Lead oxides are: PbO, PbO2, Pb3O4, Pb2O3 and the possible Pb12O19.
Trilead tetroxide
Lead tetroxide (Pb3O4) is dark brown in color.
The chemical name for red lead is lead tetroxide, which has the chemical formula Pb3O4. It is a bright red or orange crystalline compound often used as a pigment in paints and in some types of batteries.
Pb3O4 contains oxygen in the 2- oxidation state. and lead in the 2+ and 4+ oxidation states.
Pb3O4
Upon heating lead(II,IV) oxide (Pb3O4), it decomposes to form lead(II) oxide (PbO) and oxygen gas (O2). The reaction can be represented as: Pb3O4 → 3PbO + O2. This decomposition typically occurs at elevated temperatures, leading to the release of oxygen and the formation of lead(II) oxide.
Triplumbic Tetroxide = Lead(II,IV) Oxide =PbO.PbO2 = Pb3O4 = Reddish-Orange Solid
The formula of red lead, tri-lead tetroxide, is Pb3O4.
The formula for white lead is 2PbCO3 · Pb(OH)2, for red lead it is Pb3O4, and for sugar of lead it is Pb(C2H3O2)2.
These elements are: - oxygen: PbO, PbO2, Pb2O3, Pb3O4 - sulfur: PbS
Lead oxides are: PbO, PbO2, Pb3O4, Pb2O3 and the possible Pb12O19.
The nominal oxidation state of Pb in this compound is + 8/3, because oxygen is taken to have a minus two oxidation state; the four oxygen atoms therefore have a total charge of -8, and the three lead atoms must have a nominal oxidation state of + 8/3 to balance them. This variation from the normal rule that oxidation states must have whole number values arises because in Pb3O4, two-thirds of the lead atoms have an oxidation state of +2 and the remaining one-third of the lead atoms have an oxidation state of +4, thereby providing a total of +8 electric charges from three lead ions.
