Concept Introduction:
A galvanic cell is comprised of a cathode for reduction reaction and anode for the oxidation reaction. The combination of two balanced half-cell reactions gives the
(b)
Interpretation:
The oxidation and reduction half-reaction has to be identified for the redox reaction that occurs between copper metal and silver ion. Also, the reactions that occur in the anode and cathode compartments have to be stated.
Concept Introduction:
A reaction where oxidation and reduction of reactants are involved is termed as a redox reaction. The compound that undergoes oxidation is the reducing agent and the compound being reduced is termed as an oxidizing agent. The process of oxidation occurs at the anode, whereas the process of reduction occurs at the cathode.
