Question

Which of the following statement is true with regard to Daniell cell?

• A. Oxidation occurs at cathode
• B. Reduction occurs at anode
• C. \( E^\circ_{{cell}} \) is 1.1 V
• D. Electrical energy produces chemical reaction
• E. Electrolytes are aqueous solutions of CuSO\(_4\) and FeSO\(_4\).

Hint:

The standard cell potential is the difference between the reduction potentials of the two half-reactions.

Answer 1

The Correct Option is C

In a Daniell cell, the standard electrode potential \( E^\circ_{{cell}} \) is 1.1 V. The cell operates with copper and zinc electrodes, and the standard cell potential is determined by the difference in electrode potentials of the two half-reactions. 
Thus, the correct answer is (C).
