Question

# In the electrochemical cell $$Pt (s) | H_{2}(g),1atm|H^{+}(1M)||Cu^{2+}(1M)|Cu(s)$$, which one of the following statements is true?

A
H2 is cathode, Cu is anode
B
Oxidation occurs at Cu electrode
C
Reduction occurs at H2 electrode
D
H2 is anode, Cu is Cathode

Solution

## The correct option is D H$$_{2}$$ is anode, Cu is CathodeAt anode oxidation takes place and at cathode reduction take place$$\therefore H_2$$ is anode and Cu is cathodeChemistry
