Nickel sulfate absolute 6 molecules of baptize of condensate ofα - dejected and blooming aboveboard crystal, in 53 ℃intoβ - blazon blooming cellophane crystal. Stable at allowance temperature 40 ℃, become dejected blurred crystal. Absolute 7 baptize of condensate for the emerald blooming cellophane crystal. Have a candied taste. Hardly weathering. At about 100℃ loses 5 molecules of baptize of condensate as a baptize content, at 280 ℃becomes chicken blooming anhydrous. The average baleful dosage ( rats, peritoneal cavity) 500mg/kg. Have the baleful abeyant of. [3] [2] nickel sulfate anhydrous, six water, seven baptize 3, six baptize main. Anhydrous is chicken blooming crystals, the about physique of 3.68. Acrid in water, baffling in ethanol, ethyl ether. From 31.5 to 53.3 ℃for the condensate of six nickel sulfate six water, baptize is dejected or blooming aerial apparent body, the about physique of 2.07. Baptize acrid acidic, aqueous solution. Acrid in concentrated ammonia ( ammonium nickel ion accumulation ), but basal solubility in amoebic solvents ( Kraft 's failings, the filigree activity is too large. ). In 280℃to lose all the baptize of crystallization, 840 ℃begins to breach down, absolution three sulphur dioxide, into nickel oxide. Below 31.5 ℃for the condensate of seven nickel sulfate seven water, baptize for blooming cellophane crystals, candied and hardly astringent, calmly weathered, the about physique of 1.948. The temperature of 98～ 100 ℃. 103 ℃ loses 6 clear water. Acrid in baptize and ethanol, acutely simple to deliquescence. Nickel sulfate acknowledgment to dust crumb and amoebic matter, can sometimes could cause a blaze or explosion. Toxic, best acceptable absorption of 0.5mg/m3 in air.
