Use

SODIUM COBALTINITRITE is deep yellow to brown crystalline powder SODIUM COBALTINITRITE is used in the detection Potassium. Dissolve the salt (ca 60g) in H2O (300mL), filter to obtain a clear solution, add 96% EtOH (250mL) with vigorous stirring. Allow the precipitate to settle for 2hours, filter it off, wash it with EtOH (4 x 25mL), twice with Et2O and dry it in air [Glemser in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1541 1965]. It forms yellow to brown crystals which are very soluble in H2O, are decomposed by acid and form an insoluble K salt. Used for estimating potassium.
