No reaction as copper is not high enough in the electro chemical series to displace hydrogen from HCl. Uploaded By MinisterIronJay9998. No, HCl (Hydrochloric acid) does not react with Cu (Copper) because it is unreactive under normal circumstances. Copper metal does not react with acids to produce hydrogen gas.

So, zinc will react with hydrochloric acid to produce zinc chloride and hydrogen gas Zn_((s)) + 2HCl_((aq)) -> ZnCl_(2(aq)) + H_(2(g)) Zinc will reduce the hydrogen and get oxidized in the process. Answer. I also got 35.15%Cu and that was wrong also. The reactivity series follows the order: P b> H >C u. Our channel. Reaction does not occur under standard conditions... probably doesnt occur under any conditions :). No reaction - even with hot, concentrated HCl. Metals to the right of hydrogen in the electrochemical series, such as copper, silver and gold, do not react. Does zinc react with hcl? It is above copper in a metal reactivity series, so copper cannot replace the hydrogen in HCl to form CuCl2. Lv 5.
