SUMMARY
A salt bridge is essential in a galvanic cell as it prevents charge buildup by allowing ions to flow between the two half-cells. When electrons move from the anode to the cathode, a charge difference develops, which would inhibit further electron flow without the salt bridge. The salt bridge maintains electrical neutrality by enabling the movement of ions, counteracting the charge imbalance created by the electron flow. This process aligns with Coulomb's Law, which states that opposing charges create a force that resists further electron movement.
