WebMar 1, 2024 · They are both applied in the same way to establish equilibrium by transferring electrons from the cell with the lower concentration to the cell with the higher concentration. The key difference is galvanic cells can have the two half-cells with different compositions while concentration cells have two half-cells with the same composition. Top ... WebJun 22, 2024 · The electrochemical cell forces the electrons to flow through a wire as they go from Zn to the Cu 2+ ions. The electrochemical cell consists of two "half-cells" that correspond to each of the above half-cell reactions. For the half-cell corresponding to the oxidation reaction, a strip of Zn metal is placed in a solution of Zn 2+ ions.
