We have also observed that the zinc plate should not be allowed to touch the cell, as the copper will be reduced upon it and the cell destroyed. To avoid this,… … Fig. 572 is a form of the apparatus which the author has used for many years with great success, being both Fig. 572. cheap and effective, a is a large jelly-pot hold¬ B ing the copper solution ; b is a flat porous cell, about 4 inches square and half inch wide; z the zinc plate.
