STANDARD Chemistry Galvanic Cells MCQ Question
For the galvanic cell, Cu|Cu²⁺||Ag⁺|Ag. Which of the following observations is not correct?
Cu acts as anode and Ag acts as cathode.
Ag electrode loses mass and Cu electrode gains mass.
Reaction at anode, Cu → Cu²⁺ + 2e⁻
Copper is more reactive than silver.
Correct Answer
Detailed Explanation
In a galvanic cell, the anode is where oxidation occurs, and the cathode is where reduction occurs. Cu acts as the anode and loses mass, while Ag acts as the cathode and gains mass. Thus, option B is incorrect.
