Electrolysis is the process of using electrical current to cause a nonspontaneous reaction to occur. For example, water molecules do not readily decompose into hydrogen and oxygen. However, water can be decomposed using electrolysis according to the reaction 2 H₂O(1)→ 2H₂(g) + O₂(g) Because electrolysis involves the transfer of electrons, it is classified as a type of oxidation-reduction (redox) reaction. For the given reaction, identify which atoms are oxidized and which are reduced. Which atoms are oxidized? Both oxygen atoms in O₂(g). The oxygen atom in H₂O(1). Both hydrogen atoms in H₂(g). Both hydrogen atoms in H₂O(1). MacBook Pro Which atoms are reduced? Both hydrogen atoms in H₂(g). The oxygen atom in H₂O(1). Both hydrogen atoms in H₂O(1). Both oxygen atoms in O₂(g).
