Gravimetric analysis is an absolute method
WebElectrogravimetry 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 ...
