nickel sulfate usage and synthesis

general description	anhydrous nickel sulfate is a yellow-green crystalline solid. nickel sulfate can also be obtained as a hexahydrate (niso4.6h2o (cas: 10101-97-0) which is blue to emerald green, and as a heptahydrate (niso4.7h2o) (cas: 10101-98-1) , which is green. samples can contain variable quantities of water, depending on their previous exposure to moisture or conditions. all forms are mildly toxic and are carcinogenic. all are denser than water. the primary hazard is the threat to the environment. immediate steps should be taken to limit its spread to the environment. used to make other nickel compounds, in printing, and in dyeing of textiles.
air & water reactions	water soluble yielding acidic corrosive water solutions.
reactivity profile	gives an acidic solution when dissolved in water. emits highly toxic fumes of metallic nickel, oxides of sulfur, and oxides of nitrogen when heated to decomposition [lewis, 3rd ed., 1993, p. 910].
health hazard	dermatitis.
