Potassium hexachlororhodate(III) 1-hydrate may be obtained by chlorination of a mixture of powdered rhodium and potassium chloride, followed by crystallization from the reaction mixture solution in the presence of excess potassium chloride. It may also be prepared by reaction of sodium hexachlororhodate(III) solution with concentrated potassium chloride solution, followed by evaporation to incipient crystallization. Both of these methods are reported to yield potassium pentachloroaquorhodate(III) if potassium chloride is not present in excess. - Anhydrous potassium hexachlororhodate(III) is obtained by heating potassium hexachlororhodate(III) 1-hydrate at 100 to 120°. ...
