Stannous chloride (SnCl 2) is used for the same purpose. [15] Pb is used in HCl service even though the PbCl 2 formed is slightly soluble in HCl. Addition of 6–25% of antimony (Sb) increases corrosion resistance. [16] A basic chloride of lead, PbCl 2 ·Pb(OH) 2, is known as Pattinson's white lead and is used as pigment in white paint. [17]
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]
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
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.
Among the halides, the iodide is less soluble than the bromide, which, in turn, is less soluble than the chloride. [3] Lead(II) oxide is also soluble in alkali hydroxide solutions to form the corresponding plumbite salt. [2] PbO + 2 OH − + H 2 O → Pb(OH) 2− 4. Chlorination of plumbite solutions causes the formation of lead's +4 oxidation ...
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 ...
