Question

Which of the following is not true for a galvanic cell when written in an abbreviated form?

• A. Right hand electrode is a positive terminal.
• B. Right hand electrode acts as cathode.
• C. Electrons are given out in the external circuit from anode.
• D. Electrons are given out in the external circuit from cathode.

Answer 1

The correct option is D Electrons are given out in the external circuit from cathode.

A half-reaction is either just oxidation or just reduction.
At the cathode the reduction takes place, therefore, electrons are not given out in the external circuit from the cathode.

Hence, option D is the correct one.
