| | Ammonium cobalt(II) sulfate hexahydrate Usage And Synthesis |
| Description | From aqueous solutions the orange-pink heptahydrate CoSO4.7H2O crystallizes ; this is isomorphous with FeSO4.7H2O. Crystallization at 30° or by heating the heptahydrate at 41.5° yields the orange-red hexahydrate ; the monohydrate is formed above 70° and the anhydrous sulphate above 250°. This cubic anhydrous salt decomposes at 735° ; it is less deliquescent than the chloride or nitrate and is the salt used for many commercial purposes. Its solubility in water (about 36 g CoSO4 in 100 g H2O at 20°) increases with temperature ; it is insoluble in alcohol. The hydrates are magnetically dilute, having magnetic moments around 4.75 B.M. at room temperature. | | Chemical Properties | Reddish Crystal | | Uses | Ammonium cobalt(II) sulfate hexahydrate is uses as spectroscopic standard, cobalt plating, catalysis and ceramics. It is also used in pharmaceutical intermediates. |
