Question

In the metal reactivity table it is given that cooper is less reactive than hydrogen then how can it react with dilute hcl and displace hydrogen . please tell me the proper equation and tell me how can cooper displace hydrogen from dilute hcl ............ i need it fast ,,,,,,,,,, tommrow exam

Answer 1

Copper cannot displace hydrogen from a diluted acid solution .

Copper is less reactive than Hydrogen and cannot displace hydrogen in any condition.

However it displaces hydrogen from concentrated HCl to form cupric chloride and hydrogen only in special conditions.

Cu + 2HCl(concentrated) ---> CuCl2 + H2
