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.
Chemical symbols are the abbreviations used in chemistry, mainly for chemical elements; but also for functional groups, chemical compounds, and other entities. Element symbols for chemical elements, also known as atomic symbols , normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.
Chlorate is the common name of the ClO − 3 anion, whose chlorine atom is in the +5 oxidation state.The term can also refer to chemical compounds containing this anion, with chlorates being the salts of chloric acid.
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 ...
The Green Book is a direct successor of the Manual of Symbols and Terminology for Physicochemical Quantities and Units, originally prepared for publication on behalf of IUPAC's Physical Chemistry Division by M. L. McGlashen in 1969. A full history of the Green Book's various editions is provided in the historical introduction to the third edition.

Alchemical symbols were used to denote chemical elements and compounds, as well as alchemical apparatus and processes, until the 18th century. Although notation was partly standardized, style and symbol varied between alchemists.
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 ...
