In a typical electrochemical cell, which type of reaction occurs at the anode?
A
Precipitation
B
Reduction
C
Neutralization
D
Oxidation
Verified step by step guidance1
Recall the basic structure of an electrochemical cell, which consists of two electrodes: the anode and the cathode.
Understand that oxidation and reduction reactions occur at different electrodes: oxidation occurs at the anode, and reduction occurs at the cathode.
Define oxidation as the loss of electrons by a species, and reduction as the gain of electrons by a species.
Recognize that in an electrochemical cell, the anode is where the species loses electrons (oxidation), which is why the anode is the site of oxidation reactions.
Conclude that the correct type of reaction occurring at the anode is oxidation, not precipitation, reduction, or neutralization.
