The process that you saw in Activity 14.7 is used for purification of copper. A thin plate of pure copper and a thick rod of impure copper are used as electrodes. Copper from impure rod is sought to be transferred to the thin copper plate. Which electrode should be attached to the positive terminal of the battery and why?
Copper ion is definitely charged. It is attracted in the direction of the plate that is related to the terrible terminal of the battery. As copper ions are transferred to the skinny copper plate, this skinny natural copper plate need to be related to the bad terminal of the battery. Consequently, impure copper rod is hooked up to the tremendous terminal of the battery.
