As a boy, I set up my own makeshift laboratory in my parents' basement. During my early chemical investigations, I acquired some chromium(III) chloride hexahydrate, a green salt that gave an ...

Ferrous chloride (FeCl₂) added to chromium-laden brines produced by strong base anion (SBA) exchange systems reduces hexavalent chromium (Cr (VI)) to trivalent chromium (Cr (III)) and precipitates the ...

This reaction shimmers with a purple hue thanks to chromium (III) chloride (in a suspension, top; in its solid form, bottom). David Zigler’s lab at California Polytechnic State University set up ...
