salt bridge

Postby Ghadir Seder 1G » Sun Feb 23, 2020 2:09 pm

What does the salt bridge do? Why is it in the center of the cell diagram?

The salt bridge is used to maintain charge balance because the electrons are moving from one-half cell to the other.

The electrons flow from the anode to the cathode. The oxidation reaction that occurs at the anode generates electrons and positively charged ions. The electrons move through the wire, leaving the unbalanced positive charge in this vessel. In order to maintain neutrality, the negatively charged ions in the salt bridge will migrate into the anodic half cell.

The salt bridge allows ion transfer between the two solutions and is used to maintain charge !

The ultimate purpose of the salt bridge is to keep the battery running (so it doesn't run itself to equilibrium quickly). It does so by maintaining charge balance as mentioned above.

The salt bridge is used to prevent charge imbalance.
