Solutions to Chemistry MCQs

1.    In a galvanic cell, the electrons flow from:
    (a)    anode to cathode through the solution
    (b)    cathode to anode through the solution
    (c)    cathode to anode through the external circuit
    (d)    anode to cathode through the external circuit
1.    (d)    In a galvanic cell, the electrons flow from anode (which is an electron rich electrode or where oxidation occurs) to cathode (which is an electron deficient electrode or  where electrons are needed for reduction) through the external circuit (salt bridge) in a galvanic cell.
