Black Crystalline Powder | [Purification Methods]
Crystallise it from hot aqueous solution containing a few drops of HNO3 to keep it in the oxidised state. It forms small shiny red-black octahedral crystals which are dried at 100o and give a red powder on grinding [Grube in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II pp 1593-1594 1965]. |
