Sulphuric \Sul*phu"ric\, a. [Cf. F. sulfurique.]
1. Of or pertaining to sulphur; as, a sulphuric smell. [1913 Webster]
2. (Chem.) Derived from, or containing, sulphur; specifically, designating those compounds in which the element has a higher valence as contrasted with the sulphurous compounds; as, sulphuric acid. [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.

Ether \E"ther\ ([=e]"th[~e]r), n. [L. aether, Gr. a'iqh`r, fr. a'i`qein to light up, kindle, burn, blaze; akin to Skr. idh, indh, and prob. to E. idle: cf. F. ['e]ther.] [Written also [ae]ther.]
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 which case the concept of an ether pervading the vacuum may have more than metaphoric meaning. [1913 Webster +PJC]
2. Supposed matter above the air; the air itself. [1913 Webster]
3. (Chem.) (a) A light, volatile, mobile, inflammable liquid, (C2H5)2O, of a characteristic aromatic odor, obtained by the distillation of alcohol with sulphuric acid, and hence called also sulphuric ether. It is a powerful solvent of fats, resins, and pyroxylin, but finds its chief use as an an[ae]sthetic. Commonly called ethyl ether to distinguish it from other ethers, and also ethyl oxide. (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; methyl ethyl ether. The general formular for an 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. [1913 Webster +PJC]
Complex ether, Mixed ether (Chem.), an ether in which the ether oxygen is attached to two radicals having different structures; as, ethyl methyl ether, C2H5.O.CH3.
Compound ether (Chem.), an ethereal salt or a salt of some hydrocarbon as the base; an ester.
Ether engine (Mach.), a condensing engine like a steam engine, but operated by the vapor of ether instead of by steam. [1913 Webster]
