Question

The purpose of a salt bridge in an electrochemical cell is to:
Options
A provide a source of ions to participate in the reaction
B allow the flow of electrons between half-cells
C maintain electrical neutrality by allowing ion migration
Correct Answer
D serve as a site for oxidation
Correct Answer

Option C is the correct answer.

Detailed Explanation

The salt bridge contains an inert electrolyte that allows ions to flow between half-cells, preventing charge buildup and maintaining electrical neutrality, which keeps the cell reaction spontaneous.

Hint

It completes the circuit without mixing the half-cell solutions.
