Answer:
The answer is The reduction potential of copper is higher than hydrogen
Explanation:
To displace hydrogen from HCl, the metal must have lower standard electrode potential (or reduction potential) than hydrogen. Copper has higher reduction potential than hydrogen because of which copper will stay in reduced form, Cu, rather than oxidizing to Cu + or Cu 2+ . Therefore, copper does not react with HCl to give H 2 gas.
