Which half-reaction has the greatest tendency to occur at the anode in an electrochemical cell?

Cu2+ oxidizes to Cu will occur at the anode

Explanation:

Reduction occurs at the cathode and oxidation occurs at the anode

Al2+ reduces to Al3+ so this will occur at the cathode which will be on the left hand

Cu2+ oxidizes to Cu which oxidizes will occurs at the anode which is placed on the right hand

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
