Lead(IV) acetate or lead tetraacetate is an metalorganic compound with chemical formula Pb(C 2 H 3 O 2) 4. It is a colorless solid that is soluble in nonpolar, organic solvents, indicating that it is not a salt. It is degraded by moisture and is typically stored with additional acetic acid. The compound is used in organic synthesis. [2]
Lead(II) acetate is a white crystalline chemical compound with a slightly sweet taste. Its chemical formula is usually expressed as Pb(CH 3 COO) 2 or Pb(OAc) 2, where Ac represents the acetyl group. Like many other lead compounds, it causes lead poisoning. Lead acetate is soluble in water and glycerin.
Numerous organic compounds have other common names, often originating in historical source material thereof. The systematic IUPAC name is not always the preferred IUPAC name , for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid.
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.

If a pure compound is desired, PbO can be removed by a potassium hydroxide solution: PbO + KOH + H 2 O → K[Pb(OH) 3] Another method of preparation relies on annealing of lead(II) carbonate in air: 6 PbCO 3 + O 2 → 2 Pb 3 O 4 + 6 CO 2. Yet another method is oxidative annealing of white lead: 3 Pb 2 CO 3 (OH) 2 + O 2 → 2 Pb 3 O 4 + 3 CO 2 ...
Lead oxides are a group of inorganic compounds with formulas including lead (Pb) and oxygen (O). Common lead oxides include: Lead(II) oxide, PbO, litharge (red), massicot (yellow) Lead tetroxide or red lead, Pb 3 O 4, minium, which is a lead (II,IV) oxide and may be thought of as lead(II) orthoplumbate(IV) [Pb 2+] 2 [PbO 4− 4], vivid orange ...
This compound is commercially available. It may be prepared by the metathesis reaction between lead(II) nitrate and sodium oxalate: [3] Pb 2+ (aq) + C 2 O 4 2− → PbC 2 O 4 (s) A dihydrate may be formed with water solutions. But the dihydrate dehydrates in air: [4] (PbC 2 O 4 •2H 2 O (s) → (PbC 2 O 4 (s) + 2H 2 O (g)
Careful hydrolysis of lead(II) acetate solution yields a crystalline product with a formula 6PbO·2H 2 O or Pb 6 O 4 (OH) 4. [4] This material is a cluster compound, consisting of an octahedron of Pb centers, each face of which is capped by an oxide or a hydroxide. The structure is reminiscent of the Mo 6 S 8 subunit of the Chevrel phases. [5 ...
