  2. Lead(II) hydroxide - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_hydroxide

    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. [3] 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. [4]

  3. Lead(IV) hydroxide - Wikipedia

    en.wikipedia.org/wiki/Lead(IV)_hydroxide

    Lead (IV) hydroxide, Pb (OH)4, also called ortho-plumbic acid, is the notional conjugate acid of the ortho- plumbate (IV) ion, PbO4− 4, found in compounds such as calcium orthoplumbate, Ca2PbO4. [citation needed] Like its tin analog Sn (OH)4, Pb (OH)4 has not been isolated.

  4. Lead(II) acetate - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_acetate

    Lead (II) acetate is a white crystalline chemical compound with a slightly sweet taste. Its chemical formula is usually expressed as Pb (CH3COO)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.

    Lead(II) sulfate is poorly soluble, as can be seen in the following diagram showing addition of SO 24 to a solution containing 0.1 M of Pb 2+. The pH of the solution is 4.5, as above that, Pb 2+ concentration can never reach 0.1 M due to the formation of Pb(OH) 2. Observe that Pb 2+ solubility drops 10,000 fold as SO 24 reaches 0.1 M.

    Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Basic lead acetate, also known as subacetate of lead, is the inorganic compound with the formula Pb 3 (OH) 4 (O 2 CCH 3) 2. A white solid, it is one of several lead acetates. [1]

  7. Lead dioxide - Wikipedia

    Pb 12 O 19 → Pb 12 O 17 + O 2 2 Pb 12 O 17 → 8 Pb 3 O 4 + O 2 2 Pb 3 O 4 → 6 PbO + O 2. The stoichiometry of the end product can be controlled by changing the temperature – for example, in the above reaction, the first step occurs at 290 °C, second at 350 °C, third at 375 °C and fourth at 600 °C.

  8. Lead(IV) acetate - Wikipedia

    en.wikipedia.org/wiki/Lead(IV)_acetate

    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]

    3 Pb 2 CO 3 (OH) 2 + O 22 Pb 3 O 4 + 3 CO 2 + 3 H 2 O. In solution, lead(II,IV) oxide can be prepared by reaction of potassium plumbate with lead(II) acetate, yielding yellow insoluble lead(II,IV) oxide monohydrate Pb 3 O 4 ·H 2 O, which can be turned into the anhydrous form by gentle heating: K 2 PbO 3 + 2 Pb(OCOCH 3) 2 + H 2 O → Pb 3 ...
