Does copper react with hydrochloric acid?

Answer 1

No, in the sense of single replacement, but yes under a special circumstance.

Copper and hydrochloric acid do not undergo a single replacement reaction because copper is lower on the activity series than hydrogen, the active component of the acid.

The reason for this is copper normally has an electron configuration of [Ar] 4s2 3d9, which changes when exposed to a reactive species like acid to [Ar] 4s1 3d10. This gives copper half-filled subshells which are more stable and therefore less reactive.

Copper will undergo a reaction to form a complex anion if the HCl is concentrated however:

Cu(s) + HCl(aq) --> [CuCl4]2-(aq).

Note that this is not single replacement, and only occurs when the HCl is concentrated.

Answer 2

No. Copper does not react with hydrochloric acid

Answer 3

copper and hydrochloric acid do not react, however zinc and hydrochloric acid let of hydrogen (a fume). x

Answer 4

it fizzes and gas does not appear!ha ha ha

improved answer:

and it also produces sex

Answer 5

corrosion. chlorine attaches to copper making soluble copper chloride and hydrogen gas is emitted.

Answer 6

there is no reaction.
