The identity of the salt in a salt bridge is unimportant, as long as the component ions do not react or undergo a redox reaction under the operating conditions of the cell.

Question

Quizplus · Accepted Answer

The salt in a salt bridge is only used to complete the electrical circuit between the two half-cells in a galvanic cell. Therefore, its identity is not important as long as it does not interfere with the functioning of the cell. The component ions of the salt should not react or undergo a redox reaction as it can affect the potential difference of the cell.
