In this state, chromium compounds are usually coloured yellow or red (but due to charge transfer (p. 60) and not to the presence of d electrons on the chromium ion). The only halide known is the unstable chromium(VI) fluoride CrF6, a yellow solid. However, oxide halides are known, for example Cr02Cl2 ( chromyl chloride ), formed as a red vapour when concentrated sulphuric acid is added to a chromate(VI) (or dichromate) mixed with a chloride ...

Bromides and iodides give rise to the free halogens, which yield colourless solutions with sodium hydroxide if the ratio of iodide to chloride exceeds 1 15, the chromyl chloride formation is largely prevented and chlorine is evolved.J Fluorides give rise to the volatile chromyl fluoride, Cr02F2, which is decomposed by water, and hence should be absent or removed. Nitrites and nitrates interfere, as nitrosyl chloride may be formed. Chlorates must, of course, be absent. [Pg.326]
