12/6/2017· Summary: Determine what ions came from the compound. Write the reduction half-reactions that turn the neutral element into its ion by adding electron(s). Determine which half-reaction should be reversed based on which ion should be reduced or oxidized more easily, keeping in mind that the backwards (nonspontaneous) reaction to what you expect will be made to occur. And remeer, …
What is Electrolysis? - VCE Chemistry
•In electrolysis, a passage of electrical energy from a power source through a conducting liquid causes redox reactions to occur. •Electrolysis converts electrical energy into chemical energy . They are essentially opposite to the reactions occurring in galvanic cells and would not naturally occur without the appliion of electrical energy.
