Infobox references. 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.
M N−1. In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
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]
Lead(II) chromate can be produced by treating sodium chromate with lead salts such as lead(II) nitrate or by combining lead(II) oxide with chromic acid.. Related lead sulfochromate pigments are produced by the replacement of some chromate by sulfate, resulting in a mixed lead-chromate-sulfate compositions Pb(CrO 4) 1−x (SO 4) x.
Lead's close-packed face-centered cubic structure and high atomic weight result in a density [23] of 11.34 g/cm 3, which is greater than that of common metals such as iron (7.87 g/cm 3), copper (8.93 g/cm 3), and zinc (7.14 g/cm 3). [24] This density is the origin of the idiom to go over like a lead balloon.
2 PbO 2 + 4 HNO 3 → 2 Pb(NO 3) 2 + 2 H 2 O + O 2 PbO 2 + 4 HCl → PbCl 2 + 2 H 2 O + Cl 2. However these reactions are slow. Lead dioxide is well known for being a good oxidizing agent, with an example reactions listed below: [7] 2 MnSO 4 + 5 PbO 2 + 6 HNO 3 → 2 HMnO 4 + 2 PbSO 4 + 3 Pb(NO 3) 2 + 2 H 2 O 2 Cr(OH) 3 + 10 KOH + 3 PbO 2 → 2 ...
Lead(II) sulfate (PbSO 4) is a white solid, which appears white in microcrystalline form.It is also known as fast white, milk white, sulfuric acid lead salt or anglesite.. It is often seen in the plates/electrodes of car batteries, as it is formed when the battery is discharged (when the battery is recharged, then the lead sulfate is transformed back to metallic lead and sulfuric acid on the ...
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.
