(acetate, nitrate, and chlorate), sparingly soluble (chloride and fluoride), and insoluble (sulfate, carbonate, chromate, phosphate, molybdate, and sulfide). Pb(IV) salts may be obtained by the electrolysis of solutions of Pb(II) salts strongly acidified with H2SO4. The most important Pb(IV...
According to Vauquelin (1809), it was prepared by adding lead acetate or lead nitrate to potassium chromate, and the shade of the precipitate could be varied (from yellow to orange or red) by adjusting the acidity/alkalinity of the products. Lead chromate( VI), which occurs naturally as ...

On one hour treatment at 2600 F. the composition is badly blown and decomposed. EXAMPLE V Lead chloride, lead nitrate, lead sulphate There is no apparent reason why such materials 6g should heat stabilize rubber hydrohalides, and it is not definitely known that these materials retard the ...
Convert to nitrate using nitric acid; evaporate, then saturate with H2S; wash and dry the sulfide and ship to the supplier. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with ...
The above reaction may be explained by assuming lead tetroxide as formally equivalent to plumbus plumbate having a structure Pb2II[PbIVO4] in which Pb2+ dissolves in dilute nitric acid forming lead(II) nitrate while Pb4+ precipitates out as lead(IV) oxide. Lead tetroxide reacts with anhydrou...

restricted conditions for medical purposes, for example, Salvarsan is a derivative of arsenobenzene used for treating syphilis; tartar emetic, potassium antimonyl tartrate, is used as an emetic and for the treatment of some tropical diseases; and bismuth nitrate is used for treating intestinal ...
ZIF-62 glass (agZIF-62) was obtained by heating crystal ZIF-62 in a tube furnace with a ramping rate of 20 °C/min. Once the temperature reached 450 °C, the whole tube was immediately removed from the furnace and quenched in liquid nitrogen. The whole process was under argon prot...
Graphite oxide was prepared by oxidation of graphite flakes with sulfuric acid, sodium nitrate, and potassium permanganate at a ratio of 4:1:0.05 at 30° C. for 48 hours, according to the method of Hummers [U.S. Pat. No. 2,798,878, Jul. 9, 1957]. Upon completion of the reaction,...
