How can one construct a galvanic cell from two substances, each having a negative standard reduction potential?
Interpretation:
The construction of a galvanic cell from two substances, each having a negative reduction potential is to be stated.
Concept introduction:
The negative value of change in Gibbs free energy shows that the spontaneous redox reaction is taking place in the cell. For the spontaneous reaction the value of overall cell potential must be positive. So, it is the difference in the reduction potential of the two half cells that is responsible for the working of the cell.
To determine: The construction of galvanic cell from two substances, each having a negative standard reduction potential.
The potential difference is the main reason behind the working of a cell. Two half cells having a negative value of the reduction potential are stated.
The standard reduction potential of manganese is lower than cadmium and therefore manganese undergoes oxidation and acts as an anode, while cadmium undergoes reduction and acts as a cathode
