Is the following statement true or false? Concentration cells work because standard reduction potentials are dependent on concentration. Explain.
Interpretation Introduction
Interpretation:
The statement, “Concentration cells work because standard reduction potentials are dependent on concentration” is given and the authenticity of the given statement is to be stated.
Concept introduction:
The cells which contain the same type of electrodes and the electrolyte solution but differing in ion concentration are called concentration cells.
The cell potential in these cells is based upon the difference in the concentration of species involved in the reaction.
To determine: The authentication of the given statement, “Concentration cells work because standard reduction potentials are dependent on concentration”.
Explanation of Solution
The concentration cells are based on the difference in the concentration of species involved in the cell reaction. The difference in the concentration of species is the driving force for the generation of electricity that is produced because of the Gibbs free energy that is extracted from the cell because of the difference of the ion concentration...
