Gravimetry - an overview | ScienceDirect Topics

Marine gravimetry came to existence as a standard gravimetric technique some 50 years ago, even though the first attempts were made even earlier, in the 1920s and 1930s, on board submarines (Vening-Meinesz, 1932).It was clear from the beginning that marine measurements could not compete with land measurements in terms of precision. At sea, the gravimeter is subjected to the accelerations of ...

The Gravimetric Determination of Nickel

Nickel(II) forms a precipitate with the organic compound dimethylglyoxime, C4H6(NOH)2. The formation of the red chelate occurs quantitatively in a solution in which the pH is buffered in the range of 5 to 9. The chelation reaction that occurs is illustrated below. Although the loss of one proton occurs from one oxime group (NOH) on each of the two

Gravimetric Analysis

Gravimetric Analysis. Gravimetric analysis is a technique through which the amount of an analyte (the ion being analyzed) can be determined through the measurement of mass. Gravimetric analyses depend on comparing the masses of two compounds containing the analyte. The principle behind gravimetric analysis is that the mass of an ion in a pure ...

For this experiment, nickel is separated from other ions by precipitation with dimethylglyoxime (DMG) from ammonical solution using the gravimetric method. There are four fundamental types of gravimetric analysis namely physical gravimetry, thermogravimetry, precipitate gravimetry, and electrodeposition (Carmosini, Ghoreshy & Koether, 2014).

Gravimetric analysis - Wikipedia

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the …

Electrogravimetry - an overview | ScienceDirect Topics

Electrogravimetry is a method in which a metal is quantitatively electroplated on to an electrode, usually platinum. The amount of metal plated is determined by the difference in the weight of the electrode before and after electroplating. In the electroplating procedure a current is forced to flow between a platinum gauze cathode and platinum ...
