Cu(s)+2H+(aq)----> Cu2+ (aq) + H2 (g)
Do we have this reaction?
If yes, is it a displacement reaction?
If no, is something about the oxiding power of particles?
Could you explain it to me ?
Best regards

I see no reaction here at all! You start with separate Copper and Hydrogen and you end with separate Copper and Hydrogen. Are you counting 2Cu--> Cu2 and 2H--> H2 as "reactions"?

It's an ionic equation! Actually, it is supposed to like this:

2Cu (s) + 2H+ (aq) = Cu2+ (aq) + H2 (g)

I can't exactly recall where I've seen this.

Does this reaction exist?

[ek]

Isn't copper being oxidized?

Is this not an oxidation-reduction reaction?

Am I really that bad at chemistry?

:rofl:

[primarygun]

In my mind, I'm quite sure it is not a displacement reaction.
Hydrogen is above copper in the reactivity series.
I haven't learnt any oxid redox reaction so far, so I want to consult about the concept of it.
Less reactive still can reduce more reactive metal in redox reaction?

I don't think this reaction is possible.

Copper metal will not oxidize when put in H+ ions, it will reduce because it is a stronger oxidizing agent.

The two half-cells:

Cu2+ + 2e- -> Cu
H2 -> 2H+ + 2e-

And together:

Cu2+ + H2 -> Cu + 2H+

This reaction WILL occur, the one you gave WILL NOT.

Take my info with a grain of salt though. I do Physics/Astronomy, not Chemistry. But I do have a background in chem, so I'm not clueless.

Cu2+ + H2 -> Cu + 2H+
Ya! This is a displacement reaction!

[ek]

Ya! This is a displacement reaction!

I've never heard it referred to as that, but if that's what your teacher calls it, ok.
