In a voltaic cell, where does the half-reaction with the lower standard reduction potential take place?
This is a clever way of describing the anode of the voltaic cell.
You'll run into these seemingly cryptic questions a lot on exams. They demand you know every detail!
Reduction potential is the potential of a cation to be reduced. The cation with the lowest reduction potential will be oxidized to make electrons to reduce the cation with the highest reduction potential.
Oxidization occurs in the anode. Reduction occurs in the cathode.
