An electrolytic cell uses an external power source to drive a non-spontaneous chemical reaction. Electricity is used to force electrons through the cell, causing a redox reaction to occur at the electrodes. This allows for the production of new chemical compounds or the separation of substances.
In an electrolytic cell, the anode is positive.
In an electrolytic cell, the anode is designated as positive.
Oxidation occurs at the anode of an electrolytic cell.
Electrons flow from the negative electrode (cathode) to the positive electrode (anode) in an electrolytic cell. This is the opposite direction of conventional current flow.
A nonspontaneous redox reaction is driven by an external source of electrical energy, such as a battery, when a current passes through the electrolytic cell. In an electrolytic cell, the anode is positive and the cathode is negative; electrons flow from the anode to the cathode, and oxidation occurs at the anode while reduction occurs at the cathode.

A galvanic cell can become an electrolytic cell by applying an external voltage that is of opposite polarity to the cell's spontaneous voltage. This external voltage can overcome the natural tendency of the cell to generate electricity and drive a non-spontaneous chemical reaction in the reverse direction, converting it into an electrolytic cell.
