Dina widang kimia jeung manufaktur, éléktrolisis nujul ka métodeu misahkeun unsur-unsur jeung sanyawaan nu kabeungkeut sacara kimia ku cara diasupan arus listrik. Sanyawa ionik dileyurkeun dina hiji pelarut, atawa dilééhkeun ku panas,antukna ionna aya dina cairan. Arus listrik dialirkeun antara sapasang éléktroda inert nu dikeueum dina cairanana. Unggal éléktroda narik ion-ion anu muatanana sabalikna. Ion nu muatanana positip (kation) kabetot ku éléktroda négatip (katoda), sedengkeun ion nu muatanana négatip (anion) kabetot ku éléktroda positip (anoda)[1]. Énérgi nu dipikabutuh pikeun misahkeun ion-ionna antukna ngagunduk di éléktroda papasanganana asalna tina listrik. Hasil tina ieu prosés nyaéta kaserep/kabeungkeut atawa dileupaskeunana éléktron ku ion-ion ngabentuk unsur atawa sanyawa anu dipikahayang.
Oksidasi anion bisa lumangsung dina anoda, sedengkeun di katoda bisa lumangsung réduksi kation. Conto oksidasi kation di anoda:
Feaq2+⟶ Feaq3++ e−displaystyle mathrm Fe_aq^2+longrightarrow Fe_aq^3++ e^- .
Bisa ogé anion diréduksi di katoda:
Fe(CN)63−+ e−⟶ Fe(CN)64−displaystyle mathrm Fe(CN)_6^3-+ e^-longrightarrow Fe(CN)_6^4- .
Molekul nétral bisa ogé robah dina éta dua éléktroda. Conto:
+ 2e−+ 2H+⟶ displaystyle mathrm + 2e^-+ 2H^+longrightarrow
Jumlah énérgi listrik anu kudu ditambahkeun sarua jeung parobahan énérgi bébas Gibbs réaksina ditambah kaleungitan dina sistemna.
