In the electrochemical cell
` H_(2)(g) 1atm | 1H^(+)(lm) || Cu^(2+) (IM) |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

Text Solution

Verified by Experts

The correct Answer is:
D
Oxidation occurs at anode whereas, reduction occurs at cathode. Hence, `H_(2)` is anode and Cu is cathode.
