(b) A heavy, corrosive, oily liquid, H2SO4, colorless
when pure, but usually yellowish or brownish, produced
by the combined action of sulphur dioxide, oxygen
(from the air), steam, and nitric fumes. It attacks
and dissolves many metals and other intractable
substances, sets free most acids from their salts, and
is used in the manufacture of hydrochloric and nitric
acids, of soda, of bleaching powders, etc. It is also
powerful dehydrating agent, having a strong affinity
for water, and eating and corroding paper, wood,
clothing, etc. It is thus used in the manufacture of
ether, of imitation parchment, and of nitroglycerin.
It is also used in etching iron, in removing iron
scale from forgings, in petroleum refining, etc., and
in general its manufacture is the most important and
fundamental of all the chemical industries. Formerly
called vitriolic acid, and now popularly vitriol,
and oil of vitriol.
