Dissociation Electric: te turanga ariā o te Electrochemistry

dissociation Electric whai wāhi nui i roto i to tatou oraraa, ahakoa tatou te tikanga e kore e whakaaro e pā ana ki reira. E pā ana tenei āhuatanga te tai kawe, waikawa me turanga i roto i te reo wai. Mai i te ungeri tuatahi ngakau meinga e te "ora" ki te hiko i roto i te tinana tangata, e waru tekau ōrau o e ngā o wai, ki cars, waea pūkoro me kaitākaro, pūhiko rechargeable e te hunga ere pākahiko iahiko, - nga wahi katoa a tawhio noa tatou invisibly reira dissociation hiko.

Ko te Rapa exhaling purena whakaetonga kikino whakarewa i pāmahana teitei, whakarato tikanga-iahiko bauxite he "parirau" whakarewa - konumohe. ahanoa katoa a tawhio noa tatou, i te whakamahana Konqueror-whakakikoruatia hipokina ake whakakai i roto i o koutou taringa tonu fehangahangai ki rongoā ranei tai whakarewa, a konei te āhuatanga. Ehara i roto i dissociation hiko noa ako te peka katoa o te pūtaiao - Electrochemistry.

Ki runga ki te whakakāhoretanga o te whakarewa wai-rāpoi ngota mai ki here matū ki te rāpoi ngota o te rewanga, hanga solvates. Ko te nuinga o haria ki te dissociation o te tote, waikawa me turanga te wairewa. Ka rite ki te hua o tenei tukanga taea te rāpoi ngota rewanga dissociate ki katote. Hei tauira, he whakarewa wai i raro i te mana o ngā katote o Na ⁺ ko CI ^-, e te hunga i roto i te ngota puta karaihe NaCI i roto i te reo whakarewa kua i roto i te hou rite solvated (hydrated) matūriki.

tohu ana tēnei āhuatanga i roto i te ngako te tukanga o te tiango oti te kanohi ranei o te taonga rewa ki katote rite ki te hua o te rongo ki te whakarewa, a ka kua karangatia e "dissociation hiko." He tino nui mō te Electrochemistry tenei tukanga. O te faufaa nui ko te meka i te āhuatanga dissociation o te pūnaha multicomponent matatini e te takanga o te taahiraa. A, no te te kitea ano hoki tenei āhuatanga i te hua koi i roto i te maha o ngā katote i roto i te otinga, i te mea he nunui i taonga -hiko electroless.

I roto i iahiko katote i te aronga mārama o nekehanga: te matūriki ki te tiaki pai (tīhiko) - ki te kawehiko tōraro whakatupato, ka karanga te pitoiho me katote pai (ng ngota) - ki te kawehiko pitoake o tiaki ritenga, i reira e tukua e ratou. E iti a oxidized tīhiko tīhiko. Na reira, he reversible te dissociation.

Ko tētahi o nga āhuatanga taketake o tenei tukanga iahiko ko te tohu o te dissociation -hiko, faaite nei i te ōwehenga o te matūriki hydrated ki te katoa maha o ngā rāpoi ngota memeha taonga. Ko te teitei te score, te atu ko he taonga kawehiko kaha tenei. I tenei kaupapa, kua wehea matū katoa ki ngoikore, kaha reo me electrolytes kaha.

Ko te tohu o te dissociation tei runga i te āhuatanga e whai ake nei: he) te āhua o te rewanga; b) te āhua o te whakarewa, tona tamau uruhanga me te wehenga tawhiti; c) kukū o te otinga (te raro te score, te nui te tohu o te dissociation); g) Temperature o te whakakāhoretanga reo. Hei tauira, te dissociation o waikawameha ahetiki taea te whakahuatia e te tātai e whai ake:

CH ₃ COOH ⁺ H + CH ₃ tumutumu ^-

E dissociated electrolytes kaha tata irreversibly no te mea e kore e ratou wairewa noho unhydrated tīmata rāpoi ngota me ngā katote. kia hoki kia tapiritia reira e pā te tukanga dissociation matū katoa he momo pākoki katote, me te kotuari o here matū. Ko te ariā o te dissociation -hiko whakatakoto te rongonui kēmihi Swedish me ahupūngao Svante Arrhenius i 1887.
