Pb(OH) 4 Molar mass: 275.2 g·mol −1 Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol = 1 g/mol. For normal samples from earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
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]
Pb(C 2 H 3 O 2) 2 : Molar mass: 325.29 g/mol (anhydrous) 379.33g/mol (trihydrate) Appearance White powder or colourless, efflorescent crystals Odor: Slightly acetic

Lead (II) phosphate is an ionic compound with chemical formula Pb 3 (P O 4) 2. Lead (II) phosphate is a long-lived electronically neutral reagent chemical. [ 2 ] Despite limited tests on humans, it has been identified as a carcinogen based on tests on animals conducted by the EPA. [ 3 ] Lead (II) phosphate appears as hexagonal, colorless ...
Lead(II) sulfate is poorly soluble, as can be seen in the following diagram showing addition of SO 2− 4 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 2− 4 reaches 0.1 M.
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]
