black with green luster; rhomb [KIR82] | [Purification Methods]
Dissolve it in H2O and evaporate until crystals are formed. The crystals are iridescent green prisms which appear red in thin films. A possible impurity is RuO4; in this case wash with CCl4 (which dissolves RuO4). The concentration of an aqueous solution of RuO42-(orange colour) can be estimated from the absorbance at 385nm ( 1030 M-1 cm -1), or at 460nm ( 1820 M-1 cm-1). [Lee et al.
