Question

I the electrochemical cell
`H_(2(g))1atm|H^(+)(1M)||Cu^(2+)(1M)|Cu_((s))`
Which one of the following statements is true:-
A. `H_(2)` is cathode, Cu is anode
B. Oxidation occurs at Cu electrode
C. Reduction occurs at `H_(2)` electrode
D. `H_(2)` is anode, Cu is cathode

Answer 1

Correct Answer - D
`H_(2)` is anode because oxidation takes place.
Cu is cathode because reduction takes place.
