Reduction occurs at the cathode in an electrolytic cell. This is where cations in the electrolyte solution gain electrons and get reduced, leading to the deposition of a substance onto the cathode.

Electrolytic reduction is a process where a chemical compound is reduced (gains electrons) using electricity as the driving force. This occurs at the cathode of an electrolytic cell when a voltage is applied, causing a reaction to take place. This method is often used for extracting metals from their ores.

In an electrochemical cell (galvanic cell), the cathode is positive because it is where reduction occurs, attracting cations from the electrolyte. Conversely, in an electrolytic cell, the cathode is negative because it is connected to the external power source, which forces electrons into the electrode, facilitating reduction at that terminal. Thus, the polarity of the cathode changes depending on the type of cell and the direction of the current flow.
In the electrolytic cell, electrons flow from the negative terminal (cathode) to the positive terminal (anode). This flow allows for the oxidation of ions at the anode and the reduction of ions at the cathode, resulting in the desired chemical reactions to occur.
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.
