Question

Consider the following voltaic cell:(b) In which half-cell does oxidation occur?

Answer 1

At the anode, half-cell oxidation occurs in a voltaic cell.

Voltaic Cell Principle

A voltaic cell generates electricity due to the Gibbs free energy of spontaneous redox processes occurring inside the cell, which is the basis for the voltaic cell's operating principle.

Two half-cells plus a salt bridge make up the voltaic cell. An electrolyte-immersed metallic electrode is present on each side of the cell. These two half-cells are wired together to form a connection to a voltmeter.

Voltaic Cell Parts

• Copper makes comprises the cathode of a photovoltaic cell. This electrode serves as the cell's positive terminal, where reduction takes place.
• Anode: Zink metal makes up this electrode. It creates the cell's negative electrode, where oxidation takes place.
• Oxidation and reduction are divided into two discrete parts in two half-cells.
• Salt Bridge: It contains the electrolytes needed to finish the circuit in the voltaic cell.
• The flow of electrons between the electrodes occurs via the external circuit.
