Record 2 2004-01-21

English

Subject field(s)
  • Analytical Chemistry
DEF

A type of quantitative analysis involving precipitation of a compound which can be weighed and analysed after drying.

OBS

[In this method] a desired constituent is converted, usually by precipitation or combustion, to a pure compound or element, of definite known composition, and is weighed; in a few cases a compound or element is formed which does not contain the constituent but bears a definite mathematical relationship to it.

OBS

... gravimetric analysis was supplemented by volumetric or (to use a better term) titrimetric analysis ... Today these forms of chemical analysis are commonly called classical or wet method, to distinguish them from the so-called instrumental methods ...

French

Domaine(s)
  • Chimie analytique
DEF

Analyse chimique dans laquelle les teneurs des constituants sont déterminées par pesage.

CONT

La gravimétrie consiste à engager la substance à doser sous forme d'un précipité insoluble dans le milieu où il prend naissance. Après un temps convenable, on sépare par décantation, filtration ou centrifugation ce dépôt du liquide; on le lave, le sèche, le pèse. Connaissant la formule du corps pesé [...] on déduit le poids de matière analysée.

Key term(s)
  • dosage gravimétrique

Spanish

Campo(s) temático(s)
  • Química analítica
DEF

Técnica de análisis cuantitativo que permite calcular la cantidad de una sustancia por el peso de un precipitado derivado de ella, de fórmula conocida.
