Question

If a salt bridge is removed from the two half cells, the voltage ______.

Options

• drops to zero

• does not change

• increases gradually

• increases rapidly

Answer 1

If a salt bridge is removed from the two half cells, the voltage drops to zero.

Explanation:

The salt bridge maintains electrical neutrality by allowing the flow of ions between the two half-cells. If the salt bridge is removed, the flow of ions is interrupted, and charge buildup occurs in the solutions, which prevents further electron flow. As a result, the cell reaction stops, and the voltage drops to zero.
