#Zn(s) +Ni^(2+)(aq) -> Zn^(2+)(aq) + Ni(s)# Which part of the cell conducts electrons in this reaction and describes the direction of electron flow as the cell operates?
Charge flow occurs in solution by ions carrying positive or negative charges. Oxidation always occurs at the Anode and Reduction always at the Cathode. Electron flow through the metal is from the anode to the cathode.
For a Galvanic - Voltaic Cell, electron flow is from the anode to the cathode. The following diagram gives reactions at electrodes and direction of charge flow.
