A salt bridge connects the two solutions in a electrochemical cell. Recall that a salt bridge provides counterions to each solution:
The purpose of the salt bridge in an electrochemical cell isto __________.
A) provide a source of ions to react at the anode and cathode.
B) maintain electrical neutrality in the half-cells via migration of ions.
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.
