nce the hydro-gen ions in the solution are now replaced by copper ions, the substancedeposited on the cathode is pure copper instead of hydrogen. Thisis the principle involved in electroplating of all kinds. In commercialwork, the positive plate, that is, the plate at which the current entersthe… … Fig. 53. Silver-plating Bath. the other. The strength of the solution, therefore, remains unchanged.In effect, the metal is simply taken from one plate and deposited onthe other. Fig. 53 represents a silver-plating bath. The bars joinedto the anode A are of pure silver. The spoons to be plated are…
