Type: MCQ-diagram based-Hard-Class 12
Consider a diagram of a Daniell cell where the oxidation of zinc and the reduction of copper occur. Which of the following correctly describes the role of the salt bridge in this galvanic cell?
A
Maintains electrical neutrality by allowing the flow of ions.
B
Increases the external potential required to stop the cell reaction.
C
Facilitates the direct transfer of electrons between the electrodes.
D
Acts as a source of additional electrons for the copper reduction.
Correct Answer
Option A
Detailed Explanation
The salt bridge in a Daniell cell functions to maintain electrical neutrality by allowing the flow of ions, preventing the solutions from becoming charged and stopping the reaction.
