![]() These half-cells areĬonnected by a salt-bridge and the electrodes are connected through an external circuit.Įarlier in this chapter we discussed a zinc-copper cell. ![]() The anion with lower Eo value (the stronger reducing agent) is oxidized at the anode. ![]() The other half-cell contains theĬathode and an electrolyte containing the same metal cations. oxidizing agent) is reduced at the cathode. Electrons are released at the anode, making it the negative. An oxidation agent is reduced, and gains electrons in a reaction. Redox titration: Titration of a reducing agent by an oxidizing agent or titration of an oxidizing agent by a reducing agent. One half-cell contains the anode andĪn electrolyte containing the same metal cations. Anode: The anode is the electrode where oxidation occurs in an electrochemical cell. Explanation: Whenever you see 'oxidation agent', think of reduction. Galvanic cells are actually made up of two half-cells. 13.4 Processes in electrochemical cells (ESCR7) Half-cells and half-reactions (ESCR8)
