Zinc Sulfate
(ZnSO4) is a
colorless crystalline, water-soluble chemical compound. The
hydrated form of the item, ZnSO4·7H2O, the mineral
goslarite, was historically known as "white vitriol" and can
be prepared by reacting zinc with aqueous sulfuric acid.
It may also be prepared by adding solid zinc to a
copper (II)
sulfate solution.

It is used to supply zinc in animal feeds,
fertilizers, and agricultural sprays. It
is used in making lithopone, in coagulation baths for rayon,
in electrolytes for zinc plating, as a mordant in dyeing, as
a preservative for skins and leather and in medicine as an
astringent and emetic.
Zinc
is important for
growth and for the
development and
health of body
tissues.
It
is
also used to
treat and to prevent
zinc deficiency.
Another natural form of this heptahydrate is
known as mineral zincmelanterite (Zn,Cu,Fe)SO4·7H2O
(structurally different from goslarite). Lower hydrates of
zinc sulfate are rarely found in nature as minerals:
bianchite (Zn,Fe)SO4·6H2O, boyleite
(Zn,Mg)SO4·4H2O and gunningite
(Zn,Mn)SO4·H2O.
An aqueous solution of Zinc Sulphate
is
claimed to be effective at removing moss from roofs.
Spraying a mixture on moss will allow the wind to simply
blow off the remaining debris, however it is not recommended
for use on lawns as it is as effective at removing grass.
Uses:
It
is used as
raw material for production of lithopone. It is also used in synthetic fiber
industry, zinc plating, pesticides. It is mainly used in trace element
fertilizer and feed additive, etc.
It is used to supply zinc in animal feeds, fertilizers, and
agricultural sprays. ZnSO4·7H2O is used in making
lithopone, in coagulation baths for rayon, in electrolytes for zinc plating,
as a mordant in dyeing, as a preservative for skins and leather and in
medicine as an astringent and emetic.
Its spray treatments can affect growth, yield and
quality parameters of rapeseed (oil and protein). The number of seeds per
pod, the number of pods per plant and the harvest index increased
significantly with increasing Zn applications.
It is used
in pharmacology as a dietary
supplementation;
supplement to IV
solutions given for TPN; treatment
or prevention of zinc deficiencies.
Ophthalmic solution used as mild
astringent for relief of eye
irritation. It is also used for treatment of acrodermatitis enteropathica and
delayed wound healing associated
with zinc deficiency; treatment of
acne, rheumatoid arthritis, Wilson's
disease.
