In electrochemistry, a salt bridge is a U-shaped tube filled with an inert electrolyte solution. It is used to connect the two half-cells of an electrochemical cell, allowing the flow of ions between the two solutions without mixing them. The salt bridge maintains electrical neutrality in the cell and prevents the formation of concentration gradients that would hinder the cell's operation.
