Which of the following is not a function of salt bridge in an electrochemical cell ?To maintain electrical neutrality of the solutionTo complete the circuit so that current can flowTo supply ions to cathodic and anodic compartmentTo increase cell voltage

The function that is not performed by a salt bridge in an electrochemical cell is "To increase cell voltage".

Here's why:

1. "To maintain electrical neutrality of the solution": This is a function of the salt bridge. It allows the flow of ions from one half-cell to the other to balance charge and prevent the buildup of charge that would stop the reaction.

2. "To complete the circuit so that current can flow": This is also a function of the salt bridge. It completes the electrical circuit by allowing ions to flow between the half-cells, which allows the flow of current.

3. "To supply ions to cathodic and anodic compartment": This is another function of the salt bridge. It provides a medium for the flow of ions from the anode to the cathode and vice versa.

4. "To increase cell voltage": This is not a function of the salt bridge. The cell voltage (or cell potential) is determined by the difference in reduction potentials between the two half-cells, not by the presence of a salt bridge. The salt bridge simply allows the cell to operate by completing the circuit and maintaining charge balance. It does not in itself increase the cell voltage.
