Babban ka'idar amsawar electrolytic na cell electrolysis cell shine canza makamashin lantarki zuwa makamashin sinadarai da electrolyze brine don samar da NaOH, Cl2 da H2 kamar yadda aka nuna a hoton da ke sama. A cikin ɗakin anode na tantanin halitta (a gefen dama na hoton), brine yana ionized cikin Na + da Cl- a cikin tantanin halitta, inda Na + ke ƙaura zuwa ɗakin cathode (gefen hagu na hoton) ta hanyar zaɓaɓɓen membrane ionic a ƙarƙashin aikin cajin. Ƙananan Cl- yana haifar da iskar chlorine a ƙarƙashin anodic electrolysis. H2O ionization a cikin ɗakin cathode ya zama H + da OH-, inda OH- ke toshe shi ta hanyar zaɓaɓɓen membrane cation a cikin ɗakin cathode kuma Na+ daga ɗakin anode an haɗa shi don samar da samfurin NaOH, kuma H + yana haifar da hydrogen a ƙarƙashin electrolysis na cathodic.
