Electrolysis is done with an iron cathode and graphite anode, and iron gauze preventing the mixing of products, chlorine and sodium. The products of molten sodium chloride are sodium metal and chlorine gas. Sodium chloride is dissociated and exists as sodium and chloride ions in aqueous solution.

These cells are called electrolytic cells. Electrolysis is used to drive an oxidation-reduction reaction in a direction in which it does not occur spontaneously. The Electrolysis of Molten NaCl. An idealized cell for the electrolysis of sodium chloride is shown in the figure below.

Aug 27, 2023 · Electrolytic Cell. Molten salts are electrolyzed in an electrolytic cell. In an electrolytic cell, electrical energy is changed into chemical energy. A non-spontaneous reaction (chemical energy) is possible thanks to the battery’s electric energy.

Aug 29, 2023 · In an electrolytic cell (right), an external source of electrical energy is used to generate a potential difference between the electrodes that forces electrons to flow, driving a nonspontaneous redox reaction; only a single compartment is employed in most applications.

Molten sodium chloride (NaCl) can be subjected to electrolysis with the help of an electrolytic cell, as illustrated below. Here, two inert electrodes are dipped into molten sodium chloride (which contains dissociated Na + cations and Cl – anions).

Mar 14, 2025 · The electrolytic cell used in the process is called a Down's cell (see figure below). Figure \(\PageIndex{1}\): A Down's cell is used for the electrolysis of molten sodium chloride. In a Down's cell, the liquid sodium ions are reduced at the cathode to liquid sodium metal.

Nov 13, 2022 · In electrolysis, an external power source supplies the free energy required to drive a cell reaction in its non-spontaneous direction. An electrolytic cell is in this sense the opposite of a galvanic cell.

Explain electrolysis of molten NaCl. The electrolytic cell consists of a container in which fused NaCl is placed. Two graphite electrodes are immersed in it. They are connected by metallic wires to a source of direct current that is the battery.

This chemistry video tutorial focuses on the electrolysis of aqueous sodium chloride (NaCl). Hydrogen gas forms at the cathode and chlorine gas forms at the...

Metallic sodium, Na, and chlorine gas, Cl 2, are used in numerous applications, and their industrial production relies on the large-scale electrolysis of molten sodium chloride, NaCl(l). The industrial process typically uses a Downs cell similar to the simplified illustration shown below.
