WebChromium is a metallic element with oxidation states ranging from chromium( -II) to chromium(+VI) with the trivalent (III) and hexavalent (VI) sates being the most predominant. The Chemical Abstracts Service (CAS) Registry numbers for trivalent and hexavalent chromium are 16065-83-3 and 18540-29-9, respectively. WebTrivalent chromium in the sample is oxidized to the hexavalent form by hypobromite ion under alkaline conditions. The sample is acidified. The total chromium content is determined by the 1,5-Diphenylcarbohydrazide method. Determine trivalent chromium by subtracting the results of a separate hexavalent chromium test from the results of the total smart art epoxy
