Electrolysis cu anode is disolving
WebIn copper electrolysis, when a current is applied, positively-charged copper ions (called cations) leave the anode (positive electrode) and move toward the cathode (negative electrode). In this experiment (Figure 1), a U.S. penny acts as the copper source/anode and a U.S. dime WebThe net cell reaction is 2 Cl-Chloride ions + Cu 2 + Cupric ions → Cl 2 Chlorine + Cu Copper; Therefore, in the electrolysis of dilute aqueous Copper chloride, using Platinum electrodes, Cu will deposit at the cathode and dissolve at the anode to form Cu 2 + ions.
