What is Electrolytic Cell?
An electrochemical cell that uses electrical energy to drive a non-spontaneous chemical reaction (electrolysis). The power supply forces electrons to flow in the reverse direction compared to a galvanic cell. Used in electroplating, metal refining, and producing reactive metals.

Frequently Asked Questions
An electrochemical cell that uses electrical energy to drive a non-spontaneous chemical reaction (electrolysis). The power supply forces electrons to flow in the reverse direction compared to a galvanic cell. Used in electroplating, metal refining, and producing reactive metals.
Electrolytic cells are used in electroplating (Cu, Cr, Ag, Au deposition), electrolytic refining (copper purification), production of metals (Al, Na, Mg), chlor-alkali process (NaOH + Cl₂ from brine), electrolytic production of H₂ and O₂, and anodising of aluminium.
Electrolytic cells produce gases (H₂, Cl₂, O₂) that can accumulate to explosive or toxic levels. High currents cause heat buildup. Electrode materials may dissolve producing toxic heavy metal ions. Industrial electrolytic cells operate at thousands of amperes, posing severe electrical hazards.
The formula or notation for Electrolytic Cell is: ΔG > 0 (non-spontaneous)
