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]
PbO 2 + 2 OH − + 2 H 2 O → Pb(OH) 2− 6. Lead also has an oxide with mixed +2 and +4 oxidation states, red lead (Pb 3 O 4), also known as minium. Lead readily forms an equimolar alloy with sodium metal that reacts with alkyl halides to form organometallic compounds of lead such as tetraethyllead. [4]
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.
Contents. Lead carbonate. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). N verify (what is YN ?) Lead (II) carbonate is the chemical compound with the chemical formula PbCO3. It is a white, toxic solid. [ 2 ] It occurs naturally as the mineral cerussite.
3 Pb 2 CO 3 (OH) 2 + O 2 → 2 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 ...
Plumbane is an unstable colorless gas and is the heaviest group IV hydride; [8] and has a tetrahedral (T d) structure with an equilibrium distance between lead and hydrogen of 1.73 Å. [9] By weight, plumbane is 1.91% hydrogen and 98.09% lead. In plumbane, the formal oxidation states of hydrogen and lead are +1 and -4, respectively, because the ...
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 ...
