n.
The oxide of zirconium, obtained as a white powder, and possessing both acid and basic properties. On account of its infusibility, and brilliant luminosity when incandescent, it is used as an ingredient of sticks for the Drummomd light.
n.
A basic substance, C7H17NO2, formed from the growth of the typhoid bacillus on meat pulp. It induces in small animals lethargic conditions with liquid dejecta.
a.
Hence, formerly, basic, basylous, as opposed to chlorous.
n.
A green poisonous substance used as a pigment and drug, obtained by the action of acetic acid on copper, and consisting essentially of a complex mixture of several basic copper acetates.
n.
A basic silicate.
n.
Any one of a series of basic compounds which consist essentially of sulphur united with hydrocarbon radicals. In general they are oily or crystalline deliquescent substances having a peculiar odor; as, trimethyl sulphine, (CH3)3S.OH. Cf. Sulphonium.
n.
A nitrate formed from three molecules of nitric acid; also, less properly, applied to certain basic nitrates; as, trisnitrate of bismuth.
n.
A heavy yellow powder, Hg3O2SO4, which consists of a basic mercuric sulphate; -- called also turpeth mineral.
a.
Capable of neutralizing three molecules of a monacid base, or their equivalent; having three hydrogen atoms capable of replacement by basic elements on radicals; -- said of certain acids; thus, citric acid is a tribasic acid.
n.
A basic salt. See the Note under Salt.
a.
Having a valence of three; trivalent; sometimes, in a specific sense, having three hydroxyl groups, whether acid or basic; thus, glycerin, glyceric acid, and tartronic acid are each triatomic.
n.
A rare element of the chromium group found in certain minerals, as wolfram and scheelite, and isolated as a heavy steel-gray metal which is very hard and infusible. It has both acid and basic properties. When alloyed in small quantities with steel, it greatly increases its hardness. Symbol W (Wolframium). Atomic weight, 183.6. Specific gravity, 18.
n.
A salt of orthosilicic acid, H4SiO4; -- so called because the ratio of the oxygen atoms united to the basic metals and silicon respectively is 1:1; for example, Mg2SiO4 or 2MgO.SiO2.
n.
A rare element of the nitrogen-phosphorus group, found combined, in vanadates, in certain minerals, and reduced as an infusible, grayish-white metallic powder. It is intermediate between the metals and the non-metals, having both basic and acid properties. Symbol V (or Vd, rarely). Atomic weight 51.2.
n.
A hydrate; a substance containing hydrogen and oxygen, made by combining water with an oxide, and yielding water by elimination. The hydroxides are regarded as compounds of hydroxyl, united usually with basic element or radical; as, calcium hydroxide ethyl hydroxide.
