A galvanic cell has electrical potential of 1.1 V . If an opposing potential of 1.1 V is applied to this cell, what will happen to the cell reaction and current flowing through the cell ?

Text Solution

Verified by Experts

Under the conditions, the cell reaction will stop and no current will flow through the cell. For more details, consult section 3.6 (H.O.T.S. Information).
