Physical Properties
The anhydrous sulfate is a colorless rhombohedral crystalline solid; refractive index 1.658; density 3.54 g/cm3; decomposes at 600°C; soluble in water, methanol, and glycerol.
The heptahydrate, ZnSO4•7H2O, is a colorless crystalline solid; metallic taste; rhombohedral crystals; effloresces; refractive index 1.457; density 1.957 g/cm3 at 25°C; melts at 100°C; loses all Zinc Sulfate Monohydrade's water molecules at 280°C; decomposes above 500°C; very soluble in water, 96.5 g/100mL at 20°C; soluble in glycerol, 40 g/100 mL; insoluble in alcohol.
The hexahydrate, ZnSO4•6H2O constitutes colorless monoclinic or tetragonal crystals; density 2.072 g/cm3 at 15°C; loses five water molecules at 70°C; soluble in water.
White, free-flowing powder.
Soluble in water; insoluble in alcohol.
Production
Zinc Sulfate Monohydrade is produced as an intermediate in recovering zinc from mineral zinc blende, ZnS (see Zinc, Recovery).
The mineral is roasted at about 1,000°C to form zinc oxide and sulfur dioxide which, on prolonged heating in excess air, converts to zinc sulfate:
2ZnS + 3O2 → 2ZnO + 2SO2
2ZnO + 2SO2 + O2 → 2ZnSO4
In the zinc recovery process, roasted products are leached with sulfuric acid, whereupon zinc oxide is converted to sulfate.
ZnO + H2SO4 → ZnSO4 + H2O
Also, zinc sulfate can be prepared by reacting metallic zinc with dilute sulfuric acid followed by evaporation and crystallization:
Zn + H2SO4 → ZnSO4 + H2
The hydrates, especially the heptahydrate, are the primary forms used commercially.
The main application is as a coagulant in the production of rayon.
Zinc Sulfate Monohydrade is also a precursor to the pigment lithopone.
Zinc Sulfate Monohydrade is also used as an electrolyte for zinc electroplating, as a mordant in dyeing, and as a preservative for skins and leather.
Uses
Zinc Sulfate Monohydrade is a special compound fertilizer for improving rapeseed yield.
Zinc Sulfate Monohydrade may be used in the following studies:
Preparation of rayon, sprays (used in agriculture) and dyes.
As a precipitation reagent during the preparation of sample solution for ultra high pressure liquid chromatographic (UHPLC) analysis.
Preparation of ZnO nanocrystals, via sol-gel incineration technique.
Zinc Sulfate Monohydrade is used to supply zinc in animal feeds, fertilizers, and agricultural sprays.
Zinc Sulfate Monohydrade occurs in nature as the mineral, zinkosite.
The heptahydrate, ZnSO4•7H2O is the mineral, goslarite.
The salt is used as a mordant in calicoprinting, in making rayon, in preserving wood, in animal feeds, in electroplating, and in preparing many zinc compounds.
Zinc sulfate monohydrate is used in calico-printing, preserving wood and skins, electrolytes for zinc plating, bleaching paper and clarifying glue.
Zinc Sulfate Monohydrade is also used as a chemical reagent, coagulant in the preparation of rayon, mordant in dyeing and as a zinc source in animal feeds.
In medicine, Zinc Sulfate Monohydrade is used as an astringent and emetic. Further, Zinc Sulfate Monohydrade is a precursor to the pigment lithopone.
In addition to this, Zinc Sulfate Monohydrade is used to supply zinc in fertilizers, agricultural sprays, in electrolytes for zinc plating and as a mordant in dyeing.
Zinc Sulfate Monohydrade is used to supply zinc in animal feeds, fertilizers, toothpaste, and agricultural sprays.
Zinc Sulfate Monohydrade, like many zinc compounds, can be used to control moss growth on roofs.
Zinc Sulfate Monohydrade can be used to supplement zinc in the brewing process.
Zinc Sulfate Monohydrade is a necessary nutrient for optimal yeast health and performance, although Zinc Sulfate Monohydrade is not a necessary supplement for low-gravity beers, as the grains commonly used in brewing already provide adequate zinc.
Zinc Sulfate Monohydrade is a more common practice when pushing yeast to their limit by increasing alcohol content beyond their comfort zone.
Before modern stainless steel, brew Kettles, fermenting vessels and after wood, Zinc Sulfate Monohydrade was slowly leached by the use of copper kettles.
A modern copper immersion chiller is speculated to provide trace elements of zinc; thus care must be taken when adding supplemental Zinc Sulfate Monohydrade so as not to cause excess.
Side effects include "...increased acetaldehyde and fusel alcohol production due to high yeast growth when zinc concentrations exceed 5 ppm.
Excess Zinc Sulfate Monohydrade can also cause soapy or goaty flavors."
Zinc Sulfate Monohydrade is a potent inhibitor of sweetness perception for most sweet-tasting substances.
