Question: What is the role of a salt bridge in a galvanic cell?

Options:

Correct Answer: To maintain charge balance

Solution:

The salt bridge maintains charge balance by allowing ions to flow between the two half-cells.

What is the role of a salt bridge in a galvanic cell?

Correct Answer: The salt bridge maintains charge balance by allowing ions to flow between the two half-cells.

Step 1: Understand that a galvanic cell has two parts called half-cells, one for oxidation and one for reduction.
Step 2: Realize that during the chemical reactions in the half-cells, electrons move from one half-cell to the other.
Step 3: Know that as electrons move, one half-cell becomes positively charged and the other becomes negatively charged.
Step 4: Learn that the 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 flow between the half-cells to balance the charge.
Step 6: Conclude that the salt bridge is essential for the cell to keep working by maintaining charge balance.
