Characteristics-
PSA:
82.98000
XLogP3:0.4255
Appearance:Colorless solid
Density:3.8 g/cm3 @ Temp: 25 °C
Melting Point:100ºC
Boiling Point:330ºC at 760 mmHg
Water Solubility:H2O: soluble ;Solubility in water, g/100ml at 20°C: 22 (good)
Storage Conditions:There is /a/ tendency for solutions of zinc sulfate to form slight cloudiness due to seperation of basic salt formed through partial hydrolysis.
Experimental Properties:Powder or granules; loses water above 238 °C /Monohydrate/|White monoclinic crystals; mp: 238 °C (decomposes); density: 3.20 g/cu cm; solubility: 57.7 g/100 g water at 25 °C; insoluble in ethanol /Monohydrate/|Astringent, metallic taste; MP: 100 °C; density: 1.957 g/ cu cm at 25 °C/4 °C; solutions are acid to litmus /Heptahydrate/|Odorless crystals or granules or powder; efflorescent in dry air; decomposes above 500 °C; 1 gram dissolves in 0.6 mL water, 2.5 mL glycerol; insoluble in alcohol; aqueous solution is acid to litmus; pH about 4.5 /Heptahydrate/|Colorless orthorhombic crystals; mp: 100 °C (decomposes); solubility 57.7 g/100 g water at 25 °C /Heptahydrate/|Anhydrous zinc sulfate forms when its hydrates are heated above 238 °C; at about 680 °C, sulfur trioxide separates from the compound, forming 3Zn.2SO3; above 930 °C the compound is decomposed to zinc oxide; three unstable hydrates are ZnSO4.4H2O, ZnSO4.2H2O, and ZnSO4.7H2O (monoclinic)
Air and Water Reactions:Water soluble. Efflorescent in air. Aqueous solutions are acidic.
Reactive Group:Salts, Acidic
Reactivity Profile:Acidic salts, such as ZINC SULFATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
