"WebCorrect option is C) For a good salt bridge, the velocities of ions should be same. If the velocities are not same, then the ions would not be able to neutralize the charge equally in both half cells. Consequently, an opposite force would be developed that restricts the flow of current. For KNO 3, the velocities of K + and NO 3− are nearly same. " - Ion flow in salt bridge
