When there was no more plating on the platinum electrode, the stirrer was stopped, but the current was left on. The electrodes were raised from the solution and rinsed with distilled water. The power was turned off and the cathode removed. The electrode was washed with distilled waster, and then with acetone. Finally the cathode was weighed to the nearest 0.001 grams.
Electrolysis is a very good way of determining how many mole substance are present in a sample.
I know of a few electrolysis methods, and all of these methods, the electrolyte solution have slightly different characteristics. Finding information about electrolysis was not the same as the corrosion study. Most of my information came from my general chemistry books, as well as my analytical chemistry book. There were not to many articles dealing with electrolysis. The most interesting aspect of this experiment was the electrolysis portion of the experiment.
