Reactions involving electron transfers are known as oxidation-reduction reactions (or redox reactions). You may have learned in chemistry that a redox reaction is when one molecule loses electrons and is oxidized , while another molecule gains electrons (the ones lost by the first molecule) and is reduced . Jul 8, 2022 · Redox is a chemical reaction in which oxidation and reduction occur simultaneously. In a redox reaction, one substance is oxidised, and the other is reduced. Hence, oxidation and reduction proceed simultaneously. Oxidation-reduction (redox) reactions are defined as the process of electrons being transferred from one atom or ion to another. The molecule that accepts electrons is reduced because it now has a lower charge, while the molecule that donates electrons is oxidized. As electrons cannot exist independently in solution, a reduction cannot occur ...Solution. a) Since the half-equation at the left electrode is taken by convention to be oxidation, we have. Ag → Ag+ +e– Ag → Ag + + e –. At the right-hand electrode, then, we must have a reduction: 2H+ + 2e– → H2 2 H + + 2 e – → H 2.
