Gravimetriásan

Gravimetriásan is a Hungarian term that translates to "gravimetrically" in English. It refers to a method of quantitative chemical analysis that relies on measuring mass. In gravimetric analysis, the concentration of an analyte (the substance being measured) is determined by precipitating it out of solution in a pure, weighable form, or by converting it into a compound of known stoichiometry that can be weighed.

The process typically involves several steps. First, the analyte is selectively separated from other components in the sample. This is often achieved through precipitation, where the analyte reacts with another substance to form an insoluble solid. This precipitate is then filtered, washed to remove any impurities, and dried or ignited to a constant weight. The mass of the pure precipitate is then used, along with stoichiometric calculations based on its known chemical formula, to determine the amount or concentration of the original analyte in the sample.

Gravimetric analysis is known for its high accuracy and precision when performed correctly. It is a fundamental technique used in various fields, including environmental monitoring, pharmaceutical analysis, and materials science, for determining the composition of substances. While it can be time-consuming due to the multiple steps involved, its reliability makes it a valuable tool for quantitative chemical determination.
