A voltaic cell has a zinc anode and a copper cathode. They are connected by a wire but no salt bridge. What can you predict will

happen? A. Without a salt bridge to slow it down the reaction will occur faster than normal. B. The electrons will flow to the zinc anode where a negative charge will build up and eventually halt the reaction. C. None of these D. The electrons will flow to the copper cathode where a negative charge will build up and eventually halt the reaction.

The prediction is that B. The electrons will flow to the zinc anode where a negative charge will build up and eventually halt the reaction.

This is known as a chemical element, of the periodic table, that is essential to life and is one of the most widely used metals. Zinc is of considerable commercial importance.

Without the salt bridge, positive and negative charges will build up around the electrodes causing the reaction to stop.

Hence, we know that the purpose of the salt bridge is to keep the solutions electrically neutral and allow the free flow of ions from one cell to another.
