Question

Which of the following half-reactions would occur at the anode of an electrochemical cell?

A. H+(aq) + Cl− (aq) → HCl(aq)
B. Li+(aq) + e− → Li(s)
C. Cu+(aq) + e− → Cu(s)
D. Cu(s) → Cu+(aq) + e−

Answer 1

It's time you started showing some work before posting. Please talk about what you think the answer is and why or in difficult cases what it is you don't understand about the question; i.e.,why you are stuck.
For this one go through the following thoughts:
1. The anode of an electrochemical cell is where oxidation occurs (that's the definition of anode)
2. So which of the half reactions is an oxidation
3. Forgot what oxidation is? Remember the definition; oxidation is the loss of electrons.

Answer 2

This is a bit late, but the answer is D. Cu(s) → Cu+(aq) + e−

The half-reaction that occurs at the anode is oxidation, which is the loss of electrons.

Answer 3

D was correct!
