Sulphuric
(gcide) | Sulphuric \Sul*phu"ric\, a. [Cf. F. sulfurique.]
1. Of or pertaining to sulphur; as, a sulphuric smell.
[1913 Webster]

Sulphuric acid.
(a) Sulphur trioxide (see under Sulphur); -- formerly so
called on the dualistic theory of salts. [Obs.]
(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.
Fuming sulphuric acid, or Nordhausen sulphuric acid. See
Disulphuric acid, under Disulphuric.
Sulphuric anhydride, sulphur trioxide. See under Sulphur.
Sulphuric ether, common anaesthetic ether; -- so called
because made by the catalytic action of sulphuric acid on
alcohol. See Ether, 3

sulphuric acid
(gcide) | Sulphur \Sul"phur\, n. [L., better sulfur: cf. F. soufre.]
1. (Chem.) A nonmetallic element occurring naturally in large
quantities, either combined as in the sulphides (as
pyrites) and sulphates (as gypsum), or native in volcanic
regions, in vast beds mixed with gypsum and various earthy
materials, from which it is melted out. Symbol S. Atomic
weight 32. The specific gravity of ordinary octohedral
sulphur is 2.05; of prismatic sulphur, 1.96.
[1913 Webster]
Note: It is purified by distillation, and is obtained as a
lemon-yellow powder (by sublimation), called flour, or
flowers, of sulphur, or in cast sticks called roll
sulphur, or brimstone. It burns with a blue flame and a
peculiar suffocating odor. It is an ingredient of
gunpowder, is used on friction matches, and in medicine
(as a laxative and insecticide), but its chief use is
in the manufacture of sulphuric acid. Sulphur can be
obtained in two crystalline modifications, in
orthorhombic octahedra, or in monoclinic prisms, the
former of which is the more stable at ordinary
temperatures. Sulphur is the type, in its chemical

1. (Chem.) A nonmetallic element occurring naturally in large
quantities, either combined as in the sulphides (as
pyrites) and sulphates (as gypsum), or native in volcanic
regions, in vast beds mixed with gypsum and various earthy
materials, from which it is melted out. Symbol S. Atomic
weight 32. The specific gravity of ordinary octohedral
sulphur is 2.05; of prismatic sulphur, 1.96.

gunpowder, is used on friction matches, and in medicine
(as a laxative and insecticide), but its chief use is
in the manufacture of sulphuric acid. Sulphur can be
obtained in two crystalline modifications, in
orthorhombic octahedra, or in monoclinic prisms, the
former of which is the more stable at ordinary
temperatures. Sulphur is the type, in its chemical
relations, of a group of elements, including selenium
and tellurium, called collectively the sulphur group,

medium is required for the transmission of electromagnetic
waves; the modern use of the term is mostly a figurative
term for empty space, or for literary effect, and not
intended to imply the actual existence of a physical
medium. However. modern cosmological theories based on
quantum field theory do not rule out the possibility that
the inherent energy of the vacuum is greater than zero, in

radical, the structure forms a cyclic ether.

(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

1. (Physics) A medium of great elasticity and extreme
tenuity, once supposed to pervade all space, the interior
of solid bodies not excepted, and to be the medium of
transmission of light and heat; hence often called
luminiferous ether. It is no longer believed that such a
medium is required for the transmission of electromagnetic
waves; the modern use of the term is mostly a figurative
term for empty space, or for literary effect, and not
intended to imply the actual existence of a physical
medium. However. modern cosmological theories based on
quantum field theory do not rule out the possibility that
the inherent energy of the vacuum is greater than zero, in

may have more than metaphoric meaning.

(b) Any similar compound in which an oxygen atom is bound
to two different carbon atoms, each of which is part
of an organic radical; as, amyl ether; valeric ether;

is ROR', in which R and R' are organic radicals
which may be of similar or different structure. If R
and R' are different parts of the same organic
radical, the structure forms a cyclic ether.
