Electrolytic Cells

Difference between galvanic and electrolytic cells

Everything we discussed so far was about Galvanic cells which generate electric current because of spontaneous redox reactions. Galvanic cells, therefore, are characterized by positive cell potential (E) and negative free energy (ΔG). The classic example for illustrating the principle … Read more

Galvanic Cell-principle mechanism anode cathode

Galvanic cells are a type of electrochemical cell (also called voltaic cells and commonly known as batteries) where a spontaneous redox reaction generates an electric current. Another type of electrochemical cell is the electrolytic cell where, opposite to the galvanic … Read more


The Electrolysis of Molten NaCl

We have seen earlier that galvanic cells have a positive cell potential (negative Gibbs free energy) which makes them spontaneous. This means that, just like for any other process, the reverse reaction of any spontaneous redox reaction will be nonspontaneous … Read more
