radical, composed of two parts of carbon to three of hydrogen and one of oxygen. Its hydroxide is acetic acid.

f compounds analogous to vinic alcohol in constitution. Chemically speaking, they are hydroxides of certain organic radicals; as, the radical ethyl forms common or ethyl alcohol (C2H5OH); methyl forms methyl alcohol (CH3.OH) or wood spirit; amyl forms amyl alcohol (C5H11.OH) or fusel oil, etc.

used for the Powder of Algaroth, a white powder which is a compound of trichloride and trioxide of antimony. It was formerly used in medicine as an emetic, purgative, and diaphoretic.

salt of the class formed by the combination of an acid and a base, or by the union of two oxides, two sulphides, selenides, or tellurides, as distinguished from a haloid compound. [R.] Berzelius.

eries of alcohols, a transparent, colorless liquid, having a peculiar odor. It is the hydroxide of amyl. -- Amylic fermentation (Chem.), a process of fermentation in starch or sugar in which amylic alcohol is produced. Gregory.

An oxide of a nonmetallic body or an organic radical, capable of forming an acid by uniting with the elements of water; -- so called because it may be formed from an acid by the abstraction of water.

preparation or medicine containing antimony. Antimonial powder, a consisting of one part oxide of antimony and two parts phosphate of calcium; -- also called James's powder.

A compound formerly supposed to be modification of oxygen, but now known to be hydrogen dioxide; -- so called because apparently antagonistic to ozone, converting it into ordinary oxygen.

Arsenious oxide or arsenious anhydride; -- called also arsenious acid, white arsenic, and ratsbane.

- said of those compounds of gold in which this element has its higher valence; as, auric oxide; auric chloride.

- said of those compounds of gold in which this element has its lower valence; as, aurous oxide.

Self-catalysis; catalysis of a substance by one of its own products, as of silver oxide by the silver formed by reduction of a small portion of it. -- Au`to*cat`a*lyt"ic (#), a.

Of or pertaining to barium; as, baric oxide.

Symbol, Ba. Its oxide called baryta. [Rarely written barytum.]

An oxide of barium (or barytum); a heavy earth with a specific gravity above 4.

ombined with an acid, neutralizes the latter and forms a salt; -- applied also to the hydroxides of the positive elements or radicals, and to certain organic bodies resembling them in their property of forming salts with acids.

low percentage of silica, as basalt. Basic salt (Chem.), a salt formed from a base or hydroxide by the partial replacement of its hydrogen by a negative or acid element or radical.

The process of washing molten pig iron by adding iron oxide, proposed by I. Lowthian Bell of England about 1875.

y, and distinguished by its deep color, which is probably due to the presence of a little oxide of chromium.
