Ko te turanga ngoikore me tai waikawa kaha i te paparetanga

Ki te mārama me pēhea te puta tai paparetanga i roto i o ratou wairewa waiwai, ki te timata i te whakamāramatanga o te tukanga nei.

Whakamarama me rawa paparetanga

Tenei tukanga tā te pānga matū o ngā katote wai ki katote tote i hanga kia rite ki te hua o te turanga ngoikore (waikawa ranei) me te huringa tauhohenga reo. kia kia māngai Tetahi tote rite te hua o te pāhekoheko matū i waenganui i te turanga, me te waikawa. I runga anō i te mea ko tāutuhia ratou kaha he maha o rerekē o te rere tukanga.

momo o te paparetanga

I roto i te matū tirohia toru momo o tauhohenga i waenganui i nga tīhiko me te wai tote. kawea ia tukanga i roto i ki te huringa i roto i te pH, koia te riro te reira ki te whakamahi mō te whakatau i te momo rerekē hauwai taupū o tohu. Hei tauira, he tika ana te tohu waikawa papura reo waikawa whakamahia mō te waipūhuitohukonu kawakore. Te tātari atu āhuatanga tauhohenga wai o ia whakatinanatanga. Ka taea e turanga kaha, me te ngoikore kia whakaritea e te memehatanga o te tepu, me te kaha waikawa kitea e te tepu.

Tauhohenga wai o te māraa ļa

Ka rite ki te tauira o te tote taua feruri i pūhaumāota ferric (2). waihā rino (2) - he turanga ngoikore, me te waikawa kaha he waikawa pūmāota. I roto i te tauhohe ki te wai (paparetanga) Kei te hanga e o te tote taketake (hydroxychloride ferric 2) me te waikawa pūhaumāota i hanga. puta te reira i roto i te wairewa waikawa, ki te whakatau i tona taea tohu waikawa puru te whakamahi i (pH iti iho i te 7). Ko te kupu puta ia i tauhohenga wai o te māraa ļa, rite te turanga ngoikore whakamahia.

Tētahi atu tauira mo te paparetanga whakaahuatia take. A feruri i te tote konupora pūhaumāota. Konupora waihā - ko te turanga ngoikore, me te waikawa pūmāota - kaha. I roto i te tukanga o te pāhekoheko ki te pūhaumāota rāpoi wai konupora e tahuri ki te tote taketake (hydroxychloride). waihā Konupora, tona tātai te tikanga kanohi rite M (OH) _2, paku wairewa i roto i te wai, engari homai he otinga waikawa pūhaumāota kaha, he taiao waikawa.

Ko te tauhohenga wai o te anion

āhuatanga te whakatinanatanga anō e te tauhohenga wai o te tote i hanga nei e te turanga kaha (alkali) me te waikawa ngoikore. Ka rite ki te tauira mo tenei take whakaaro tatou te konutai pākawa waro.

Tenei tote kua he turanga konutai kaha, me te waikawa carbonic ngoikore. Ngā pāhekoheko ki te rāpoi ngota wai hua ki te hanganga o te tote waikawa - te konutai pākawa waro, i.e. i te paparetanga ko te anion. I tua atu, i hanga ai i roto i te otinga o te konutai waihā, e homai i te otinga o tētahi taiao kawakore.

Ko tētahi atu tauira i roto i tenei take. Pāhare pāporo sulfite - he tote, i hanga nei e te turanga kaha - waihā konurehu, me ngoikore waikawa sulfurous. I roto i te tukanga o te pāhekoheko ki te wai (hoki paparetanga) i hanga te pāhare pāporo hydrogensulfite (tote waikawa) me te konurehu waihā (alkali). Te reo i roto i te otinga, ko te kawakore, ka taea ka oti te whakau te whakamahi i te waipūhuitohukonu.

paparetanga oti

Ko te tote o te waikawa ngoikore me te turanga ngoikore te whakamamaetia paparetanga oti. Whakamātauria ki te kitea i roto i te mea i tona āhuatanga, me he aha ngā hua e hanga e rite ki te hua o te tauhohenga matū.

Te tātari i te tauhohenga wai o te turanga ngoikore, me te waikawa ngoikore i roto i tauira sulfide konumohe. Tenei tote konumohe waihā i hanga, i te mea he turanga ngoikore, me te waikawa ngoikore, hauwai sulfide. Na roto i te tauhohe ki te wai kitea paparetanga oti, hua i roto i te sulfide hau hanganga hauwai, me te konumohe waihā hohenga. puta taua taunekeneke me mo te māraa ļa me anion, reira, whakaaro taua paparetanga te oti.

Ano i roto i te taunekeneke hi'oraa maitai o tenei momo ki te wai tote e taea arahi sulfide konupora. Hei wāhanga o te tote, ko te waihā konupora, tātai reira - Mg (OH) 2. Ko te turanga ngoikore, rewakore i roto i te wai tenei. I tua atu, waikawa hydrosulphuric reira, i te mea ngoikore i roto i sulfide konupora. Na roto i te tauhohe ki te wai e wahi paparetanga oti (mō te māraa me anion), ki te hanga i te sulfide konupora waihā hohenga, me te hauwai tukua i roto i te puka o te hau.

Ki te whakaaro tatou te tauhohenga wai o te tote i hanga nei ki te waikawa kaha, me te turanga kaha, kia tuhia te reira e kore e turuturu i te reira. Taiao i roto i rongoā o tai pērā i pūhaumāota, te konutai pākawa, pāhare pāporo, tonu kūpapa.

mutunga

Kaha, me te ngoikore turanga, tai waikawa nei e hanga e, pā te hua o te reo paparetanga tauhohenga i roto i te otinga hua. Kei te whānui tohaina taua tukanga i roto i te natura.

He tino nui i roto i te huringa matū o kirinuku o te whenua te tauhohenga wai. Oku i ai e sulfides whakarewa, paku wairewa i roto i te wai. Ka rite ki to ratou tauhohenga wai puta hanganga o hauwai sulfide, ona tukunga i roto i te puia i runga i te mata o te whenua.

toka magnesium i roto i te waihā whakawhiti, meinga whakangaromanga o te kamaka āta. Hei tauira, pērā i te malachite kohuke, ko reira te hua o pākawa paparetanga parahi.

tukanga paparetanga tino e hoki wahi i roto i te moana. ngā hauwai pākawa waro o te konupora me te konupūmā, e kua tangohia i roto i o te wai, i te reo paku kawakore. I raro i taua tikanga, tukanga pai o te ahotakakame e wahi i roto i te tipu moana, kei te whanake hakune kaiao moana.

He poke o te wai me te konupūmā me te konupora tai te hinu. I roto i te tukanga o te para hinu, ko reira ratou taunekeneke ki te kohu wai. I roto i te paparetanga, kua hanga e hauwai pūhaumāota, e, runga i te tauhohenga ki te whakarewa puta whakangaromanga taputapu.
