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 following reaction. 2H_2O (l) rightarrow 2H_2(g) + O_2(g) Since electrolysis involves the transfer of electrons, it is classified as a type of oxidation-reduction (redox) reaction. For the reaction above, identify which atoms are oxidized and which are reduced. Which atoms are oxidized? Both oxygen atoms in O_2 (g). The oxygen atom in H_2O (l). Both hydrogen atoms in H_2O (l). Both hydrogen atoms in H_2 (g). Which atoms are reduced? Both hydrogen atoms in H_2 (g). Both hydrogen atoms in H_2O (l). The oxygen atom in H_2O (l). Both oxygen atoms in O_2 (g).
