Web27. jan 2024 · Redox reactions are titled as such because during the reaction one chemical species is oxidized while another is simultaneously reduced. But what does that mean? When something is oxidized, it has lost electrons and when something is reduced, it has gained electrons. WebThere are three H atoms in the ammonia molecule, so the total oxidation number for hydrogen 3 (+1) = +3. The sum of the oxidation numbers in a neutral compound must equal zero, so the oxidation number for N is -3: 3 (+1) + (-3) = 0. This is a redox reaction, in which nitrogen is reduced from N₂⁰ to N⁻³, and H₂⁰ is oxidized to H⁺¹.
