WebHow does copper react with dilute acid? - In the series the metals above hydrogen react with dilute acids to give salt and hydrogen gas. ... So, copper cannot replace the hydrogen in HCl to form CuCl2 . Cu(s)+HCl(aq) noreaction. Hence, when copper (Cu) reacts with hydrochloric acid (HCl) there will be no reaction. Web2 days ago · No, Copper does not react with non-oxidizing acid like dilute sulphuric acid, hydrochloride, hydrobromide, etc because its reduction potential is higher than that of hydrogen. Therefore, copper is present below hydrogen in the reactivity series of metal. Copper in the pure state cannot displace hydrogen atoms from acid.
