Anode Material Series
The anode is connected to the positive pole of the power supply in the electrolytic cell. The current of the power supply enters the electrolytic cell through the anode along the external circuit, and the electrons leave the anode under the action of the external power supply and flow to the cathode through the external circuit. The anode is insoluble in the electrodeposition process and used only as a conductor and for the discharge of associated ions in solution, and what occurs instead is the process of oxidation of negative ions into neutral molecules for precipitation or oxidation of low-valence positive ions into high-valence ones.
