82164181 Lab Report On Gravimetric Determination Of Nickel
Gravimetric analysis is one of the suitable experimental methods for determining the presence of a substance through the weighing process. The technique was used to determine the percentage of nickel using dimethylglyoxime (DMG) and ammonium hydroxide, which later proved that the samples used contained a small percentage of Ni.

Gravimetric Analysis Principle with Types, Advantages and
Gravimetric analysis relies on the contrast of the masses of two analyte-containing compounds. The idea behind gravimetric analysis is that it is possible to calculate the mass of an ion in a pure compound and then use it to calculate the mass percentage of the same ion in a specified volume of an impure compound.
