He tawhā nui te pūmanawa hiko i roto i te matū hiko e ine ana i te kaha o te hiko ki te kukume, ki te tuku rānei i ngā irahiko. He mea nui te ine i te pūmanawa hiko i roto i ngā tono ahumahi, rangahau pūtaiao, me te hangarau, pērā i ngā pākahiko, ngā pūtau wahie, te waikura, me te tātari matū. Ka matapakihia e tēnei tuhinga ngā mātāpono taketake o te ine i te pūmanawa hiko, ōna tikanga ine, me ngā tono mahi e whakamahi ana i tēnei ine.
Ngā Mātāpono Taketake o te Pūmanawa Hiko
Ko te pūmanawa hikohiko te rerekētanga o te pūmanawa hiko i waenga i te hikohiko me te otinga hikohiko e karapoti ana. He hua tēnei o ngā tauhohenga redox e puta ana i te mata o te hikohiko. Kāore e taea te ine tika i tēnei pūmanawa engari ka inehia tonutia e pā ana ki te hikohiko tohutoro. Nō reira, ka whakamahia te ariā o te pūmanawa hikohiko paerewa (E°), ina inehia te pūmanawa hikohiko ki te hikohiko hauwai paerewa (SHE).
Pūmanawa hiko paerewa (E°): Koinei te pūmanawa hiko ina kei raro te hiko i ngā āhuatanga paerewa, arā, he otinga 1 M, he hau i te pēhanga o te 1 atm, me te pāmahana o te 298 K.
Tikanga Ine Pūmanawa Hiko
1. Irahiko Tohutoro
I roto i tētahi pūnaha irahiko, he mea nui kia whai i tētahi irahiko tohutoro e mōhiotia ana te pūmanawa. E rua ngā irahiko tohutoro e whakamahia whānuitia ana:
– Te Irahiko Hauwai Paerewa (SHE): Ka whakamahia te SHE hei pūwāhi tohutoro kore mō te ine i te pūmanawa o ētahi atu irahiko. Ko te SHE he konukawata kua pania ki te hau hauwai i raro i te pēhanga o te 1 atm kua rumakina ki roto i te otinga waikawa me te kukū katote hauwai o te 1 mol/L.
– Irahiko Calomel Kūkū (SCE): He maha ngā whakamahinga o te SCE i roto i ngā taiwhanga nā tōna pumau me tōna māmā. He ranunga o te calomel (Hg2Cl2) me te mercury i roto i te wairewa KCl kūkū kei roto i tēnei irahiko.
2. Raupapa Ine
Hei ine i te pūmanawa hikohiko, he ara iahiko māmā ēnei:
– Te irahiko hei ine (irahiko mahi)
– Irahiko tohutoro
– Ngā taputapu ine pūmanawa, pērā i ngā mita ngaohiko, ngā mita potentiometer rānei
Te tukanga:
1. Ka toua te irahiko mahi ki roto i te otinga irahiko.
2. Ka toua hoki te hiko tohutoro ki roto i te wairewa kotahi, mā roto rānei i te piriti tote mēnā he rerekē te wairewa.
3. Mā te whakamahi i te mita pūmanawa, tuhia te uara pūmanawa i waenganui i te irahiko mahi me te irahiko tohutoro.
3. Te Whakatikatika me te Whakatikatika
I muri i te whiwhinga o te uara pūmanawa, me whakataurite ki te hiko tohutoro e whakamahia ana, inā koa mēnā he hiko ehara i te SHE te whakamahi. Tērā pea me whakatikatika te pāmahana nā te mea ka rerekē te pūmanawa o te hiko i runga i te pāmahana.

1. Ngā Pūnaha Pūngao: Ngā Pūhiko me ngā Pūtau Wahie
He mea nui te pūmanawa hikohiko i roto i te hoahoa me te whai huatanga o te pākahiko. Hei tauira, ka mahi ngā pākahiko lithium-ion i runga i te rerekētanga pūmanawa i waenga i ngā hikohiko anode (hei tauira, te karāhe) me te katote (hei tauira, te LiCoO2). Mā te ine tika i tēnei pūmanawa hikohiko ka taea te hanga rauemi hou ki te whakapai ake i te kiato me te roa o te ora o te pākahiko.
Pūtau Wahie
Ka whakawhirinaki hoki ngā pūtau wahie, pērā i ngā pūtau wahie hauwai, ki ngā pūmanawa hiko hei huri i te pūngao matū ki te pūngao hiko. Mā te mōhio ki ngā pūmanawa hiko i te anode me te cathode ka āwhina i te whakapai ake i te whai huatanga o ngā tauhohenga redox.
2. Te Parenga Waikura me te Katorika
Ko te waikura te tukanga o te pirau o ngā rauemi nā ngā tauhohenga matū ki te taiao, e uru ana ki ngā tauhohenga redox. Ka whakamahia ngā inenga pūmanawa hiko hei aroturuki me te whakahaere i te waikura.
Te Tiakitanga Katorika: Ka whakamahia tēnei tikanga hei tiaki i ngā hanganga whakarewa mā te whakamahi i tētahi pūmanawa kino ki runga i a rātou, kia puta ai he katorika e kore e waikura. Me ine tonu i te pūmanawa hiko hei whakarite i te tiakitanga whai hua.

Ko te Potensyometry he tikanga tātari e whakamahi ana i ngā inenga pūmanawa hiko hei whakatau i te kukū o ngā katote motuhake i roto i tētahi otinga. He tino whai hua i roto i te tātari matū taiao me te matū koiora-ngota. Hei tauira, ka whakamahia he mita pH, he mita pūmanawa hiko, hei aroturuki i te kukū o ngā katote hauwai i roto i tētahi otinga.
4. Pūoko Koiora
He taputapu tātari te pūoko koiora e whakakotahi ana i tētahi huānga koiora me tētahi taputapu whakawhiti hiko.
