Question

In an operating electrochemical cell the function of
a salt bridge is to...
O allow a non-spontaneous reaction to occurs
O permit the migration of ions within the cell
allow hydrolysis to occurs
O transfer electrons from the cathode to the anode​

Answer 1

Answer:

The salt bridge allows ion migration and maintains electrical neutrality in two solutions. The salt bridge provides electrical contact between the two solutions and completes the electrical circuit. It prevents the mixing of electrode solutions.

Without the salt bridge, the solution in the anode compartment would become positively charged and the solution in the cathode compartment would become negatively charged. This will cause charge imbalance and the electrode reaction would quickly come to a halt.

Answer 2

Answer:

Concept:

An electrochemical cell is a device that may either generate electrical energy from chemical reactions or use it to initiate chemical reactions. Voltaic and galvanic cells generate an electric current, whereas electrolytic cells induce chemical reactions such as electrolysis. A standard 1.5 volt cell better source needed] for consumer usage is a popular example of a galvanic cell. In two solutions, the salt bridge facilitates ion migration while maintaining electrical neutrality. The salt bridge completes the electrical circuit by establishing electrical contact between the two solutions. It keeps electrode solutions from combining.

Answer:

In two solutions, the salt bridge facilitates ion migration while maintaining electrical neutrality. The salt bridge completes the electrical circuit by establishing electrical contact between the two solution. It keeps electrode solutions from combining. The salt bridge's job is to keep the solutions electrically neutral while allowing ions to freely pass from one cell to the next. Without the salt bridge, negative poles will build up around the electrodes, halting the process. Even without salt bridge, the solution in the anodic chamber would become positively charged while the liquid in the cathode compartment was becoming negatively charged, and the electrode reaction would come to a halt fast due to the charge imbalance.
