WebMar 10, 2024 · Oxidation is generally defined as losing electrons and reduction as gaining elections. The two processes oxidation and reduction occur together; thus one compound is reduced in the process of oxidizing another. Chlorine bleaches are oxidizing agents; when chlorine reacts with water, it produces hydrochloric acid and atomic oxygen. WebSep 16, 2024 · Because the metals have lost electrons to oxygen, they have been oxidized; oxidation is therefore the loss of electrons. Conversely, because the oxygen atoms have gained electrons, they have been reduced, so reduction is the gain of electrons. For every oxidation, there must be an associated reduction. tesla wlan update
