Ko te ariā o te dissociation -hiko. He whakamārama ohie o tukanga matatini

Ki te wā mahi "dissociation -hiko" pūtaiao i te mutunga o te rautau tekau mā iwa. Tona ahua, e ua faahepohia tatou e te kēmihi Swedish Arrhenius. Te mahi i runga i te raruraru o kawehiko i roto i nga tau 1884-1887, whakaurua ia e ia ki te whakaahua i te āhuatanga o te ionization i roto i rongoā me i te hanganga o te rewanga. Ko te tikanga o tenei tītohunga e faaoti i te reira ki te whakamārama i te whāwehe o te rāpoi ngota ki katote, huānga he tiaki pai kino ranei.

Ko te ariā o te dissociation -hiko whakamārama te kawe ia o te tahi mau rongoā. Hei tauira, ki te pāhare pāporo pūhaumāota he āhuatanga o tenei wāwāhi tote o ngā rāpoi ngota mō te konurehu katote he tiaki ki te tohu KCl «me" (te māraa) me te katote māota, he tiaki ki te tohu "tango" (anion). Waikawa pūmāota motumotuhia HCl ki te māraa ļa (hauwai katote) me te anion (pūhaumāota katote), he otinga o te konutai waihā Naho arata'i ki te konutai katote me te anion rite katote waihā. Ko te tikanga matua o te ariā o te dissociation -hiko whakaahua te whanonga o ngā katote i roto i rongoā. E ai ki tenei ariā, neke ratou rawa noa i roto i te otinga, ka tautoko noa te topata iti o te otinga e te tohatoha ōrite o oppositely whakatupato utu hiko.

faataa te ariā o te hanganga o te dissociation -hiko o electrolytes i roto i wairewa waiwai e whai ake. Ko te ahua o katote free tohu te whakangaromanga o te rauemi karaihe ripekapeka. awe tenei tukanga mā te whakamemehatanga te taonga i roto i te wai e te pānga o ngā rāpoi ngota whakarewa neke (i roto i to tatou hi'oraa whakaaro tatou wai). Na e taea ki te whakaiti i te vai te kaha o te attraction hiko i waenganui i te katote i roto i te pae wini whakakahokaho karaihe ratou, kua whakawhiti katote hua ki te kaupapa noa o te otinga. tomo nga katote noa te taiao o te neke rāpoi wai. Tenei puka anga a tawhio noa ratou, te ariā o te dissotsiatsiinazyvaet -hiko hydrated.

Ko whakamārama te ariā o te dissociation -hiko Arrhenius te hanganga o electrolytes kore anake i roto i rongoā. Ka taea e te wini whakakahokaho karaihe kia ngaro i raro i te mana o te pāmahana. Whakawera i te karaihe, te tiki matou te pānga o oscillations kaha o te katote i roto i nga pae wini whakakahokaho, āta ārahi ki te whakangaromanga o te karaihe, me te putanga o ngohe ana katoa titoa o katote.

E hoki ki nga rongoā ki te kia whakaaro rawa motuhake o te taonga, e karanga matou he whakarewa. Ko te māngai tino nui o tenei hapu, ko te wai. Ko te āhuatanga matua ko te aroaro o ngā rāpoi ngota dipole, i.e. ina te pai whakatupato tetahi pito o te rāpoi ngota, me te tahi atu tōraro. Ko te muingota wai tutuki tino enei whakaritenga, engari e kore ko te wai anake te whakarewa.

Ko te tukanga o te dissociation -hiko kia meinga i te whakarewa neke kore-waiwai, mo te tauira, wai hāorarua whanariki, haukini wai, a pera atu. Ko e te reira te wai i roto i tenei raupapa te wahi matua rite tona rawa ki te haaparuparu (tareka) te attraction hiko, me te whakangaro i whakaaturia te wini whakakahokaho karaihe e tino mārama. Na reira, e korero e pā ana ki ngā rongoā, te tikanga o matou he reira he wai wai.

He ako tino o te āhuatanga o electrolytes whakaaetia ki te neke ki te ariā o te kaha, me te tohu o te dissociation. I raro i te tohu o te dissociation o kawehiko auraa te te ōwehenga o rāpoi dissociated ki to ratou maha katoa. electrolytes Potential, pae tenei tau whakarea i te kore ki te kotahi, me te tohu o te dissociation, i te mea e rite ana ki te kore, tohu e mahi tatou ki-electrolytes kore. I runga i te hua i roto i te tohu o te dissociation o te pānga pai te whakanui ake i te pāmahana o te otinga.

whakatau kaha electrolytes te tohu o dissociation, whakaratohia he kukū tamau me te pāmahana. electrolytes kaha i te tohu o te dissociation, tata kotahitanga. Ko reira pai tai wairewa, kawakore, waikawa.

Ko te ariā o te dissociation -hiko reira taea ki te whakamārama i te whānuitanga o ngā tītohunga, e kua ako i roto i te anga o te ahupūngao, matū, whaiaroaro o ngā tipu me ngā kararehe, Electrochemistry ariā.
