Question

Based on the diagram and given reaction, Which of the compound will be placed on the positive and negative terminal? Explain briefly the reason

Zinc reacts with copper sulphate, because zinc is more reactive electrochemically than copper. Therefore, when a strip on zinc in placed in a copper sulphate solution, the strip is "solvated" in to solution according to the equation: CuSO4(aq) + Zn(s) → Cu(s) + ZnSO4(aq) Also we can write this reaction into two half reactions Cu²+ (aq) + 2e →→ Cu (s) Zn(s) →→→ Zn²+ (aq) + 2e- (reduction). (oxidation).
