Given the electrochemical cell reaction: Zn(s) + Ni2+ (aq) → Zn2+ (aq) + Ni(s)

Which species is the reducing agent?

Explanation:

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.

Explanation:

For a Galvanic - Voltaic Cell, electron flow is from the anode to the cathode. The following diagram gives reactions at electrodes and direction
