Question

Which of the following is/are function(s) of salt-bridge ?

• A. It completes the electrical circuit with electrons flowing from one electrode to the other through external wires and a flow of
  ions between the two compartments through salt-bridge.
• B. It minimises the liquid-liquid junction potential.
• C. Both ((A) and (B) are correct
• D. None of these

Answer 1

The correct option is C Both ((A) and (B) are correct

Salt-bridge completes the electrical circuit with electrons flowing from one electrode to the other through external wires and a flow of ions between the two compartments through salt-bridge and it also minimises the liquid-liquid junction potential by providing a path for flow of current where ions have comparable ionic mobilities like in $KN{O}_3.$
