Consider a magnesium–iron galvanic cell consisting of a magnesium electrode in a solution of 1 m mgso4 and an iron electrode in a solution of 1 m feso4. each electrode and its electrolyte are separated by a porous wall, and the whole cell is at 25°c. both electrodes are connected with a copper wire.
(a) which electrode is the anode?
(b) which electrode corrodes?
(c) in which direction will the electrons flow?
(d) in which direction will the anions in the solutions move?
(e) in which direction will the cations in the solutions move?
(f ) write the equation for the half-cell reaction at the anode.
(g) write the equation for the half-cell reaction at the cathode.
