The voltammogram for 20.00 mL of solution that was 3.65 x 10-3M in Cd2+ gave a wave for that ion with a limiting current of 31.3 A. Calculate the percentage change in concentration of the solution if the current in the limiting current region were allowed to continue for a) 5 min; b) 10 min and c) 30 min.
