Indium and Cadmium ions in 0.1 M HCl give peaks at potentials -0.557 V and -0.597 V by differential pulse polarographic analysis. When a standard solution containing 0.4 ppm of indium is analysed, it gave peak current (in arbitrary units) corresponding to 100.25 at -0.557 V and 43.75 at -0.597 V. A standard solution containing 0.4 ppm of Cd gave ip 29.52 at -0.557 V and 64.8 at -0.597 V. What is the concentration of indium and cadmium in a sample if the peak current is 190 at -0.557 V and 120 at -0.597 V.
