Ko te irahiko whiriwhiri ion he pūoko hikohiko e rite ana tōna pūmanawa ki te logarithm o te ngohe ion i roto i tētahi otinga. He momo pūoko hikohiko e whakamahi ana i te pūmanawa membrane hei whakatau i te ngohe ion, i te kukū rānei i roto i te otinga. Nō te irahiko membrane,nā wai Ko te wāhanga matua ko te kiriuhi aro o te irahiko. Ko te tikanga irahiko whiriwhiri katote he peka o te tātaritanga potentiometric. E whakamahia whānuitia ana i roto i te tikanga potentiometric tika me te titration potentiometric. Ko te tauira whai huatanga e whakaahuatia ana i roto i tōna wwhānuitanga tono ide. Hei tāpiri atu, it ka taea te ine te kukū o ngā iona motuhake i roto i te otinga. Hei tāpiritanga, ikāore a t e pāngia e tetae me pōuriuri me ētahi atu āhuatanga o matū matū.
Te tukanga ine o te irahiko whiriwhiri katote
Ina pā ngā katote inehia i roto i te otinga irahiko ki te irahiko, ka puta te hekenga katote i roto i te puna wai o te matrix kiriuhi irahiko whiriwhiri katote. He pūmanawa kei roto i te huringa utu o ngā katote heke, e whakarerekē ana i te pūmanawa i waenga i ngā mata o te kiriuhi. Nō reira, ka puta he rerekētanga pūmanawa i waenga i te irahiko ine me te irahiko tohutoro. He mea tino pai kia rite te rerekētanga pūmanawa i puta i waenga i te irahiko whiriwhiri katote me ngā katote hei ine i roto i te otinga ki te whārite Nernst, arā,
E=E0+ log10a(x)
E: Pūmanawa i inehia
E0: Pūmanawa hiko paerewa (pūmau)
R: Pūmau hau
T: Te pāmahana
Z: Te uara ā-ionic
F: Pūmau Faraday
a(x): te mahi ā-iona
Ka kitea ko te pūmanawa hiko i inehia he rite ki te logarithm o te mahi a ngā iona "X". Ina noho pūmau te tauwehenga mahi, ka rite anō hoki te pūmanawa hiko ki te logarithm o te kukū iona (C). Mā tēnei, ka taea te whiwhi i te mahi, i te kukū rānei o ngā iona i roto i te otinga.
