gravimetric analysis A method for quantitative chemical analysis in which the substance to be estimated is converted to a substance which can be separated pure and entire, and which is then weighed. Commonly a highly insoluble precipitate is formed, filtered off, washed, and dried (see dehydration). The weight of substance sought is calculated from the weight and composition of the precipitate.
