The purpose of the salt bridge in an electrochemical cell is to ____.
A. maintain electrical neutrality in the half-cells via migration of ions
B. provide a source of ions to react at the anode and cathode
C. provide oxygen to facilitate oxidation at the anode
D. provide a means for electrons to travel from the anode to the cathode
E. provide a means for electrons to travel from the cathode to the anode

Respuesta :

Answer:

A. maintain electrical neutrality in the half-cells via migration of ions

Explanation:

Salt bridge -

For an electrochemical reaction , involving an anode and a cathode , both the electrodes are connect via a salt bridge to complete the circuit for the reaction .

One of the very important use of a salt bridge is to maintain the electrical neutrality of the respective half cells , which is achieved by the movement of ions .

Hence , from the given options , the correct option is ( a ) .
