Which half reaction can occur at the anode in a voltaic cell

Oxidation is the half reaction that can occur at the anode in a voltaic cell.

Explanation:

In electrodes which is metal strip in voltaic cell the reactions occurs. The two electrodes placed one in each half-cell. The reduction reaction occurs at cathode and oxidation occurs at anode.

A half reaction is either the oxidation or reduction reaction component of a redox reaction. A half reaction is obtained by considering the change in oxidation states of individual substances involved in the redox reaction. Half-reactions are often used as a method of balancing redox reactions.

In an oxidation half reaction, an atom loses electron (s). When an element is oxidized it loses a specific number of electrons.
