CHEMICAL AND PHYSICAL PROPERTIES

Physical Description	Nickel sulfate hexahydrate appears as blue or emerald-green crystalline material. Toxic and carcinogenic. Two known phases. Alpha-form (blue tetragonal) converts to beta-form (green monoclinic) at 127.9 °F. Becomes blue and opaque at room temperature. Odorless. Sweet astringent taste. Somewhat efflorescent. Greenish-yellow anhydrous salt is formed at 536 °F. (NTP, 1992)
Boiling Point	Decomposes at 1544 °F (NTP, 1992)
Melting Point	127.9 °F (transition point) (NTP, 1992)
Solubility	greater than or equal to 100 mg/mL at 68 °F (NTP, 1992)
Density	2.07 (NTP, 1992) - Denser than water; will sink
Vapor Pressure	0 mmHg at 68 °F Essentially (NTP, 1992)
