Where do metals get deposited during electrolytic reduction?

During electrolytic reduction, the metals are deposited at the cathode (the negatively charged electrode).

  • Electrolytic reduction is a type of electrolysis in which electric current is passed through an ionic substance (molten or dissolved ), producing a chemical reaction at the electrodes and decomposing the materials.
  • It is used for highly electropositive metals like Potassium, which cannot get reduced in aqueous solutions.
  • For example electrolysis of sodium chloride is taken
  • NaCl → Na +(l) + Cl(l)

    At cathode: reduction of 2Na+(l) + e→ Na(l)

    At anode: oxidation of 2Cl(l) → Cl2(g) + 2e

    Net Reaction is written as: 2Na +(l) + 2Cl(l) → 2Na(l) + Cl2(g)
