The mixture of the metallic ions is taken in the Polarographic cell. The jockey is allowed to move from H to I and for each position of jockey, we find out the reading to voltmeter (v) and galvanometer. Then we plot a graph of current in $$\mu A$$ V/S potential applied. The Polarogram is consisting of series of waves. Each wave corresponds to the reduction of one particular metal ion species. The polarogram obtained when a solution containing different metal ions at concentration of 104 gm ions per $$dm^3$$ is electrolyzed with 0.1 N KCl as the supporting electrolyte.

For grids that are the same from the smallest of devices to the largest, use the .col and .col-* classes. Specify a numbered class when you need a particularly sized column; otherwise, feel free to stick to
