The experimental time dependences of the fraction of chloride oxidized agrees with the theory based on the assumption of quasiequilibrium between the gas and salt phases when a current of bromine is passed through a cell containing fused KCl....

The pale-brown bromine monofluoride (BrF) is unstable at room temperature, disproportionating quickly and irreversibly into bromine, bromine trifluoride, and bromine pentafluoride. It thus cannot be obtained pure. It may be synthesised by the direct reaction of the elements, or by the comproportion...
An efficient oxidation of sulfides with air catalyzed by the combination of potassium nitrate with pyridinium tribromide under transition-metal-free conditions was reported. By replacing pyridinium tribromide with bromine, the reaction system was also useful in the oxidation of alcohols. All reactions aff...
[2](iii)The addition of concentrated sulfuric acid to solid sodium bromide, NaBr, produces brown fumes and an acidic gas that decolourises acidified potassium manganate(VII)solution.This acidic gas is a significant contributor to acid rain.Write the equation for the reaction of concentrated ...
and where said step of polymerizing employs a lanthanide-based catalyst system that includes the combination of or reaction product of ingredients including (a) a lanthanide compound, (b) an aluminoxane, (c) an organoaluminum compound other than an aluminoxane, and (d) a bromine-containing com...
(p,n)76Br reaction offers here an alternative to get a pure product, albeit on account of a lower production yield. A rather recent comprehensive article discusses the efficiency of the proton-induced nuclear reactions in detail and points out that alternative3He- and d-induced reactions, as ...
The maximum or minimum time of reaction after all the hydrochloric acid has been added depends on the nature of the sample; usually a few minutes suffices.Add an excess of potassium iodide to the mixture in BC (Note 7). After shaking, transfer the contents to a titration flask and wash ...
The heats of reaction of rubidium and cesium metals and hydrides with water at 25° have been measured. The values determined, in kilocalories per mole, are: M(c) + 3001 · H2O(l) = MOH-3000H2O + 1/2H2(g), ΔH° = -46.615 ± 0.016, ΔH°... SR Gunn - 《J.phys.chem》 ...
where dihydrogenphosphate was used as the regenerable absorbent to remove ammonia from wastewater, and produced ammonia liquor. We call this kind of SGM process with a reversible reaction occurring in the stripping solution as a reversible-based supported gas membrane process (RSGM). In this study,...
