So water is also capable of undergoing oxidation, and water likewise, is also capable of undergoing reduction. So let's look at oxidation first. So what atoms are able to oxidize? Well, this atom could oxidize, and a water atom could oxidize. Now, if this atom decides to oxidize, this is our oxidation reaction. Now, if water decides to oxidize, namely the oxygen decides to oxidize, then this is our oxidation reactions.
