Question
What happens when copper is reacted with HCl and $HNO _3$ ?
✓
Answer
There is no reaction of copper with HCl because $H ^{+}$ions cannot oxidize Cu , that is Cu can't give electrons to $H ^{+}$as it is less reactive than hydrogen. But when Cu is reacted with $HNO _3$, it gets oxidized by $NO _3{ }^{-}$ ions instead of reacting with $H ^{+}$.
