"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

Webso that the electrons will flow through an external circuit as shown in Figure 1. A salt bridge is necessary for charge balance: in this case sulfate ions flow from the copper to the zinc compartment. The electrochemical cell shown in Figure 1 can be represented by the following shorthand: Zn (s) !Zn+2 (aq) !! Cu+2 (aq) ! Cu (s) WebA salt bridge serves as an electrical conductor in electrochemical cells to allow the flow of ions and maintain a neutral charge within the cell. The flow of ions creates an electrical …

Web5 mei 2024 · Fe is the anode and Sn is the cathode; NO3- ions flow into half-cell compartment (A) and Na ions flow into half-cell compartment (B). Explanation: The purpose of a salt bridge in a voltaic cell is not to move electrons from the electrolyte, it's main function is the maintenance of charge balance between the half cells .The electrons flow … WebWell as you know the salt bridge’s function is to maintain electric neutrality in the half cells while completing the current. Ions from the salt bridge flow to the solution to counter oxidation at the anode and reduction at the cathode and maintain electric neutrality. The salt bridge ionic concentration can be slightly too low: ions don’t ...
