In a Daniell cell, what is the role of the salt bridge?

Step 1: Understand that a Daniell cell has two parts called half-cells, one with zinc and one with copper.
Step 2: Know that during a chemical reaction in the cell, electrons flow from the zinc half-cell to the copper half-cell.
Step 3: Realize that as electrons move, the zinc half-cell loses positive ions, making it more negative.
Step 4: Understand that the copper half-cell gains positive ions, making it more positive.
Step 5: Recognize that this creates an imbalance of charge between the two half-cells.
Step 6: Learn that the salt bridge is a tube filled with a salt solution that connects the two half-cells.
Step 7: Know that the salt bridge allows ions to flow between the half-cells to balance the charge.
Step 8: Conclude that the salt bridge maintains charge neutrality, which is essential for the cell to function properly.
