Chromyl chloride perchlorate

Effect of Heat. In 1910, R. Roth reported that the blue-green hexahydrate turns green on heating. At 110° w is lost, then perchloric ac, followed by decompn at 210° into chromyl chloride and chromic ac (Ref 3)... [Pg.632]

Take a 100 ml sample of water in a beaker. Add a crystal of sodium sulphite (this minimises the loss of hexavalent chromium as chromyl chloride on heating). Add 1 ml of concentrated sulphuric acid, heat the sample on a hot plate and evaporate until fuming. Cool. Add 25 ml of distilled water and 2 ml of concentrated nitric acid. Evaporate to near dryness on a hot plate. Cool. Add 25 ml of distilled water, 1 ml of concentrated nitric acid and 1 ml of perchloric acid. Evaporate on a hot plate to near dryness. Cool. Take up residue into 1% hydrochloric acid and filter if necessary. [Pg.71]
