gravimetric analysis उदाहरण वाक्य

The precipitation of this compound from solutions of hexachloroplatinic acid was formerly used for the determination of potassium by gravimetric analysis.
Gravimetric analysis usually only provides for the analysis of a single element, or a limited group of elements, at a time.
Gravimetric analysis is one of the most precise of the common methods of chemical analysis, but it is time-consuming and labour-intensive.
Gravimetric analysis, due to its high degree of accuracy, when performed correctly, can also be used to calibrate other instruments in lieu of reference standards.
It is convenient for collecting a precipitate directly within the vessel in which it is to be dried, possibly ashed, and finally weighed in gravimetric analysis.

The atomic weight is 107.8682 ( 2 ) u; this value is very important because of the importance of silver compounds, particularly halides, in gravimetric analysis.
A crucible with a bottom perforated with small holes which is designed specifically for use in filtration, especially for gravimetric analysis as just described, is called a Gooch crucible after its inventor, Frank Austen Gooch.
CsClO 4 is the least soluble of the alkali metal perchlorates ( followed by Rb, K, Li, and Na ), a property which may be used for separatory purposes and even for gravimetric analysis.
In gravimetric analysis, which consists on precipitating the analyte and measuring its mass to determine its concentration or purity, coprecipitation is a problem because undesired impurities often coprecipitate with the analyte, resulting in excess mass.
Properly calibrated microbalances, capable of reading in the range of micrograms ( 10 " 6 g ) can also be used effectively for gravimetric analysis of low-volume micropipettes, but only if environmental conditions are under strict control.
