WebBubbles of hydrogen form on the surface of the zinc. The reaction is: Zinc + Sulfuric acid → Zinc sulfate + Hydrogen. Zn (s) + H 2 SO 4 (aq) → ZnSO 4 (aq) + H 2 (g) In test tube 2, copper is the catalyst for the reaction, and the reaction should be faster than in test tube 1, but may not be as fast as test tube 3. WebSignificanceAqueous zinc-ion batteries (ZIBs) possess the advantages of low cost and high safety. However, their Zn anodes are usually confronting with the challenge of side reactions and Zn dendri... Aqueous zinc-ion batteries are emerging as one of the most promising large-scale energy storage systems due to their low cost and high safety.
