抄録

A small tank for plating by electrolysis was manufactured with a view to saving reagent and observing the change on the surface of metal which was plated. The volume of plating solution was 3〜4 ml when using this small tank. The conditions adequate for using a small tank for plating copper and nickel on copper which had already been mentioned in texts or experimental books were determined, and an experiment of plating iron which so far had not been mentioned could be devised. Class experiments of plating copper, nickel and iron on copper were carried out by using this small tank. The plating experiment was come out by observing the change on the metal surface through the microscope. Students were interested in the fact that copper covered by a thin iron film was attracted by a magnet.
