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).
Lead tetrachloride, also known as lead (IV) chloride, has the molecular formula PbCl 4. It is a yellow, oily liquid which is stable below 0 °C, and decomposes at 50 °C. [ 2 ] It has a tetrahedral configuration, with lead as the central atom. The Pb– Cl covalent bonds have been measured to be 247 pm and the bond energy is 243 kJ⋅mol −1.
Infobox references. Lead (II) chloride (PbCl 2) is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water. Lead (II) chloride is one of the most important lead -based reagents. It also occurs naturally in the form of the mineral cotunnite.
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 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.
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]
The capped square antiprismatic anion [Pb 9] 4− from [K(18-crown-6)] 2 K 2 Pb 9 ·(en) 1.5 [81] Some lead compounds exist in formal oxidation states other than +4 or +2. Lead(III) may be obtained, as an intermediate between lead(II) and lead(IV), in larger organolead complexes; this oxidation state is not stable, as both the lead(III) ion and ...
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.
