What is the purpose of a salt bridge in an electrochemical cell?

Step 1: Understand that an electrochemical cell has two parts called half-cells.
Step 2: Know that each half-cell has a different charge because of chemical reactions happening there.
Step 3: Realize that if one half-cell becomes too positive or too negative, it can stop the reaction.
Step 4: Learn that a salt bridge is a tube filled with a salt solution that connects the two half-cells.
Step 5: Understand that the salt bridge allows ions to move between the half-cells.
Step 6: Know that this movement of ions helps keep the charges balanced in both half-cells.
Step 7: Conclude that the purpose of the salt bridge is to maintain charge balance so the electrochemical cell can keep working.
