SUMMARY
The selection of salts for a salt bridge in electrochemical cells is crucial to prevent unwanted reactions while maintaining ionic balance. The primary function of the salt bridge is to neutralize the solution, preventing the buildup of anions or cations that could halt cell operation. Ideal salts are those that do not react with the components of the cell, and their selection often involves comparing reduction potentials to ensure minimal interference. Artful selection of salts can yield effective results, although challenges arise in cells with transport mechanisms.
