The
production of sulfuric acid has come
to be accepted throughout the world as a
reliable barometer of industrial activity.
Its universal use has made it indispensable,
in the widest sense of the world, in chemical
and process industries. Sulfuric acid is
a strong acid i.e. is in aqueous solution
it’s largely changed to hydrogen ions and
sulfate ions. Each molecule gives 2 hydrogen
ions and thus sulfur
ic acid is dibasic acid.
Sulfuric acid is a multipurpose product
and finds its application as a dehydrating agent,catalyst, active reagent in chemical
processes, solvent and absorbent etc. It
is used in process industries from very
dilute concentrations, for pH control of
saline solutions to strong fuming acids
used in the dye, explosives and pharmaceutical
industries, in grades of less exacting specifications
for use in steel, heavy chemical and super
phosphate industries. Sulfuric acid is not
a one use product like a returnable steel
drum, after initial use in some phases of
explosives, petroleum and dye industries,
the sulfuric acid is recovered in a firm
often unsuitable for use in the same process
but, of strength and grades entirely suitable
for use in other process industries.
