Question: What is the primary function of a salt bridge in an electrochemical cell?

Options:

Correct Answer: To maintain charge balance

Solution:

The primary function of a salt bridge is to maintain charge balance by allowing ions to flow between the half-cells.

What is the primary function 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 (one is positive and the other is negative).
Step 3: Realize that as a chemical reaction happens in the half-cells, ions are produced, which can create an imbalance of charge.
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 to balance the charge.
Step 6: Conclude that the primary function of the salt bridge is to maintain charge balance in the electrochemical cell.
