If a salt bridge is not used between two half cells, what happens to the voltage?
Drops to zero
Does not change
The correct option is B Drops to zero The purpose of a salt bridge is not to move electrons from the electrolyte, rather maintain charge balance because the electrons are moving from one-half cell to the other. The electrons flow from the anode to the cathode thus if a salt bridge is removed between the half cells, the voltage becomes zero.
