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. inclusion\u0027s m5WebThe spontaneous flow of electrons from anode to cathode and the migration of cations and anions in the solutions and salt bridge generates a current with a voltage near the theoretical E o cell = 1.10 V at room temperature.

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 ... WebNaNO3 and K2SO4 are commonly used in salt bridges. The solute in the salt bridge solution should be a very soluble ionic compound containing unreactive ions KNO3(aq). The solution in the salt bridge must be capable of dissociating into ions, cations and anions. These flow to either of the half-cells in order to balance them and keep the ...

WebIn the salt bridge, the positive ions move towards positive electrode as at the positive electrode (cathode) undergo reduction of metal ion take place which makes the solution excess with anion.
