Of or pertaining to sulphur; as, a sulphuric smell.
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.
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 (a).
... bead by adding a little turpentine to it. Well! what then? Turpentine is a very healthy diuretic. It is given to infants to kill worms in very large doses. Then, again, vitriol is spoken of; but so strong is sulphuric acid, that it would clearly render these spirits quite unpalatable. I do not affirm that the art of adulteration may not occasionally be had recourse to, even with criminal intentions, for such cases have been brought under the notice of the authorities; but I do not believe ... — The International Monthly, Volume 3, No. 1, April, 1851 • Various Read full book for free!

When the weather is fine, all the works are in full operation, and good profits are realized by furnishing brimstone for the manufacture of sulphuric acid. ... — Mexico and its Religion • Robert A.

... two of the most common kitchen-garden crops. If we submit a Cabbage to the destructive agency of fire, and analyse the ashes that remain, we shall find in them, in round numbers, eight per cent. of sulphuric acid, sixteen per cent. of phosphoric acid, four per cent. of soda, forty-eight per cent. of potash, and fifteen per cent. of lime. It is evident that we cannot expect to grow a Cabbage on a soil which is destitute of these ingredients, to say nothing of others. ... — The Culture of Vegetables and Flowers From Seeds and Roots, 16th Edition • Sutton and Sons Read full book for free!
... unanimous in their account of Plattner's proceedings. He poured a little of the green powder into a test-tube, and tried the substance with water, hydrochloric acid, nitric acid, and sulphuric acid in succession. Getting no result, he emptied out a little heap—nearly half the bottleful, in fact—upon a slate and tried a match. He held the medicine bottle in his left hand. The stuff began to smoke and melt, and then exploded ... — The Country of the Blind, And Other Stories • H. G. Wells Read full book for free!
... oil by means of borax in certain proportions. They do not, however, readily mix, especially in cold weather. The translator does not seem to be aware that borax is the solvent for lac; she mentions "sulphuric or muriatic acid," but water with borax alone will dissolve lac before it boils.[7] We would venture to recommend some experiments with lac dissolved in borax to water-colour painters. It is by no means improbable that some of the old Greek paintings are in ... — Blackwood's Edinburgh Magazine, Volume 57, No. 356, June, 1845 • Various Read full book for free!
