Lead perchlorate trihydrate is produced by the reaction of lead(II) oxide, lead carbonate, or lead nitrate by perchloric acid: . Pb(NO 3) 2 + HClO 4 → Pb(ClO 4) 2 + HNO 3. The excess perchloric acid was removed by first heating the solution to 125 °C, then heating it under moist air at 160 °C to remove the perchloric acid by converting the acid to the dihydrate.
Thus while carbon tetrachloride is a stable compound, with lead the oxidation state +2 is favored and PbCl 4 quickly becomes PbCl 2. Indeed, the inert pair effect causes lead to favor its +2 oxidation state: Pb atom loses all its outermost p electrons and ends up with a stable, filled s subshell. [7]
Because of the tremendous diversity allowed, in combination, by the valences of common atoms and their ability to form rings, the number of possible cyclic structures, even of small size (e.g., < 17 total atoms) numbers in the many billions. Cyclic compound examples: All-carbon (carbocyclic) and more complex natural cyclic compounds
2 PbCl 2 + 4 RMgBr → R 4 Pb + Pb + 4 MgBrCl 3 PbCl 2 + 6 RMgBr → R 3 Pb-PbR 3 + Pb + 6 MgBrCl [12] These reactions produce derivatives that are more similar to organosilicon compounds, i.e. that Pb(II) tends to disproportionate upon alkylation. PbCl 2 can be used to produce PbO 2 by treating it with sodium hypochlorite (NaClO), forming a ...
Although thermodynamically a mild reductant, Fe 2+ ion exhibits a stronger trend to remain coordinated by water molecules to form the corresponding hexa-aquo complex in solution. The high activation energy of the cation binding with perchlorate to form a transient inner sphere complex more favourable to electron transfer considerably hinders ...
The chlorate ion cannot be satisfactorily represented by just one Lewis structure, since all the Cl–O bonds are the same length (1.49 Å in potassium chlorate [1]), and the chlorine atom is hypervalent. Instead, it is often thought of as a hybrid of multiple resonance structures:
It dissolves in nitric acid with the evolution of nitric oxide gas to form dissolved Pb(NO 3) 2. 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 ...
