Lead(IV) hydroxide, Pb(OH) 4, also called ortho-plumbic acid, is the notional conjugate acid of the ortho-plumbate(IV) ion, PbO 4− 4, found in compounds such as calcium orthoplumbate, Ca 2 PbO 4. [ 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]
Lead azide was a component of the six .22 (5.6 mm) caliber Devastator rounds fired from a Röhm RG-14 revolver by John Hinckley, Jr. in his assassination attempt on U.S. President Ronald Reagan on March 30, 1981. The rounds consisted of lead azide centers with lacquer-sealed aluminum tips designed to explode upon impact.
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]
Infobox references. 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) 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 ...
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 ...
Lead chromate adopts the monazite structure, meaning that the connectivity of the atoms is very similar to other compounds of the type MM'O 4. Pb(II) has a distorted coordination sphere being surrounded by eight oxides with Pb-O distances ranging from 2.53 to 2.80 Å. The chromate anion is tetrahedral, as usual. [3]
