External circuit chemistry
WebAn electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur. The external energy source is a voltage applied between the cell′s two electrodes; an anode (positively charged electrode) and a cathode (negatively charged electrode), which are immersed in an … WebAt the anode - Anions (negative ions) move to the anode and give up electrons, forming atoms or molecules (discharged). - Oxidation occurs at the anode. In the external circuit - Electrons flow from the positive terminal to the negative terminal of the battery. At the cathode - Cations (positive ions) move to the cathode and receive electrons, forming …
