Question

why does not Cu react with HCL even on heating

Answer 1

HELLO...
GM..
HERE IS UR ANSWER ...
As copper is less reactive than hydrogen, therefore it will not liberate hydrogen gas from the acids like HCl, HNO, HSO etc. But sulphuric acid is a strong oxidising agent, therefore it will oxidise copper metal to Cu2+ ion. ... Hence it does not react withcopper metal at all.
