In a voltaic cell, where does the oxidation take place?
a. anode
b. cathode
c. electrolyte solution
d. salt bridge
e. wire

An electrode is strip of metal on which the reaction takes place. In a voltaic cell, theoxidation and reduction of metals occurs at the electrodes. There are two electrodes in a voltaic cell, one in each half-cell. The cathode is where reduction takes placeand oxidation takes place at the anode.

So, the answer is A. anode

Hope this helps:-)
