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.
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]
The basic hydroxo complex [Pb 6 O(OH) 6] 4+ is a cluster of six lead centres with metal–metal bonds surrounding a central oxide ion. The six hydroxide groups lie on the faces of the two external Pb 4 tetrahedra. In strongly alkaline solutions soluble plumbate ions are formed, including [Pb(OH) 6] 2−. [28]
White lead is the basic lead carbonate 2PbCO 3 ·Pb (OH) 2. [1] It is a complex salt, containing both carbonate and hydroxide ions. White lead occurs naturally as a mineral, in which context it is known as hydrocerussite, [1] a hydrate of cerussite. [2] It was formerly used as an ingredient for lead paint and a cosmetic called Venetian ceruse ...
3 Pb + 8 H + + 8 NO − 3 → 3 Pb 2+ + 6 NO − 3 + 2 NO + 4 H 2 O. When heated with nitrates of alkali metals, metallic lead oxidizes to form PbO (also known as litharge), leaving the corresponding alkali nitrite. PbO is representative of lead's +2 oxidation state. It is soluble in nitric and acetic acids, from which solutions it is possible ...
Lead (IV) acetate or lead tetraacetate is an metalorganic compound with chemical formula Pb (C2H3O2)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.
