volumetric analysis 名詞
Vol·u·met·ric a. Of or pertaining to the measurement of volume.
Volumetric analysis Chem., that system of the quantitative analysis of solutions which employs definite volumes of standardized solutions of reagents, as measured by burettes, pipettes, etc.; also, the analysis of gases by volume, as by the eudiometer.
A·nal·y·sis n.; pl. Analyses
1. A resolution of anything, whether an object of the senses or of the intellect, into its constituent or original elements; an examination of the component parts of a subject, each separately, as the words which compose a sentence, the tones of a tune, or the simple propositions which enter into an argument. It is opposed to synthesis.
2. Chem. The separation of a compound substance, by chemical processes, into its constituents, with a view to ascertain either (a) what elements it contains, or (b) how much of each element is present. The former is called qualitative, and the latter quantitative analysis.
3. Logic The tracing of things to their source, and the resolving of knowledge into its original principles.
4. Math. The resolving of problems by reducing the conditions that are in them to equations.
5. (a) A syllabus, or table of the principal heads of a discourse, disposed in their natural order. (b) A brief, methodical illustration of the principles of a science. In this sense it is nearly synonymous with synopsis.
6. Nat. Hist. The process of ascertaining the name of a species, or its place in a system of classification, by means of an analytical table or key.
Ultimate, Proximate, Qualitative, Quantitative, and Volumetric analysis. Chem. See under Ultimate, Proximate, Qualitative, etc.
Grav·i·met·ric a. Chem. Of or pertaining to measurement by weight; measured by weight. -- Grav*i*met*ric*al*ly adv.
Gravimetric analysis Chem., analysis in which the amounts of the constituents are determined by weight; -- in distinction from volumetric analysis.
n 1: determination of the volume of gases (or changes in their
volume) during combination
2: quantitative analysis by the use of definite volumes of
standard solutions or reagents
