It forms yellow crystals from water. Recrystallise it two or three times from H2O and dry it over H2SO4. Its solubility at 20o is 30.96g/100g H2O, and it is insoluble in EtOH. Aqueous solutions tend to decompose especially in the presence of light or on heating when Cr(OH)3 separates. [Hein & Herzog in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II pp 1373-1374 1965.] |
