Cu is less reactive than hydrogen
WebThere is only one positive ion that can discharge at the cathode and that is hydrogen. Hydrogen will undergo reduction (gain electrons) to become hydrogen atoms. 2H + + 2e – ——————-> H 2 At the anion, OH will be discharged, as it is less reactive than the sulfate. OH will undergo oxidisation to lose electrons and become water and ... WebMay 13, 2015 · Zinc reacts with hydrochloric acid to produce hydrogen gas because it's more reactive than hydrogen, and thus displaces the latter from an acid. By comparison, copper cannot displace hydrogen from HCl because it's less reactive than hydrogen. So, zinc will react with hydrochloric acid to produce zinc chloride and hydrogen gas Zn_((s)) …

WebApr 11, 2024 · Introduction. Increased attention has been devoted to the efficient utilization of hydrogen fuel due to the continuously growing demand for renewable energy sources and ongoing efforts to reduce fossil fuel usage [1].A hydrogen fuel cell is a promising technology for hydrogen utilization by converting hydrogen energy into electricity [2, … WebSome metals such as Copper (Cu), Mercury (Hg), Silver (Ag), Gold (Au) and Platinum (Pt) are less reactive than hydrogen. So, they can not replace hydrogen from acids. Metals which lie above the hydrogen in the reactivity series, they can replace hydrogen from acids easily. Zn (s) + 2 HCl → ZnCl + H 2 (g) Zinc reacts with HCl and releases H2 gas.
