- Replacement - n. - The act of replacing.
- Replacement - n. - The removal of an edge or an angle by one or more planes.
- Tetrabasic - a. - Capable of neutralizing four molecules of a monacid base; having four hydrogen atoms capable of replacement by bases; quadribasic; -- said of certain acids; thus, normal silicic acid, Si(OH)4, is a tetrabasic acid.
- Metathesis - n. - The act, process, or result of exchange, substitution, or replacement of atoms and radicals; thus, by metathesis an acid gives up all or part of its hydrogen, takes on an equivalent amount of a metal or base, and forms a salt.
- Triglyceride - n. - A glyceride formed by the replacement of three hydrogen atoms in glycerin by acid radicals.
- Osteoplastic - a. - Of or pertaining to the replacement of bone; as, an osteoplastic operation.
- Tetracid - a. - Capable of neutralizing four molecules of a monobasic acid; having four hydrogen atoms capable of replacement ba acids or acid atoms; -- said of certain bases; thus, erythrine, C4H6(OH)4, is a tetracid alcohol.
- Hydrosulphide - n. - One of a series of compounds, derived from hydrogen sulphide by the replacement of half its hydrogen by a base or basic radical; as, potassium hydrosulphide, KSH. The hydrosulphides are analogous to the hydrates and include the mercaptans.
- Bevelment - n. - The replacement of an edge by two similar planes, equally inclined to the including faces or adjacent planes.
- Tribasic - 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.
- Dibasic - a. - Having two acid hydrogen atoms capable of replacement by basic atoms or radicals, in forming salts; bibasic; -- said of acids, as oxalic or sulphuric acids. Cf. Diacid, Bibasic.
- Truncation - n. - The replacement of an edge or solid angle by a plane, especially when the plane is equally inclined to the adjoining faces.
- Amine - n. - One of a class of strongly basic substances derived from ammonia by replacement of one or more hydrogen atoms by a basic atom or radical.
