Waimeha papare: teuteu me te whakamahi

Ngā pūreirei - reira rongoā kei roto pūnaha pūreirei. pūnaha moka i huaina ranunga i roto i nei te hanganga kei te ōwehenga ine waikawa ngoikore whakaritea, me o ratou tai ki turanga kaha ranei turanga ngoikore, me o ratou tai ki waikawa kaha. Taua rongoā i te kukū pūmau o te H + katote i whakarewa kūpapa te faatarapape ore (te wai) me te tāpiri ki a ratou i te nui etahi o waikawa kaha turanga ranei.

He waimeha papare i nga wai o te moana, rongoā oneone me i roto i ngā kaiao ora. whakahaere ēnei pūnaha mana mahi e tautoko kaha reo tauhohenga i te uara i whakaritea e tika ana mō te takanga angitu o tauhohe pūkoro. E whakarōpūtia waimeha papare ki waikawa me te taketake. tuatahi e taea tētahi tauira hei pūnaha moka tāpia, te tuarua - te haukini. Wehe i ngā pūreirei māori, me te horihori. He otinga moka māori he toto kei roto hydrocarbonate, Phosphate, te pūmua, pūtoto, me he pūnaha moka waikawa. kia moka tāwhaiwhai moka tāpia, arā, o CH3COOH.

Āhuatanga o te hanganga ā-me te tikanga o te mahi o nga pūnaha papare whakaaro tatou te hi'oraa o te pūnaha papare tāpia: tāpia waikawa / konutai tāpia. I roto i te reo wai nei ki raro i te wāhanga pūnaha moka dissociation -hiko. tāpia Konutai rite te tote o te waikawa ngoikore me he turanga kaha rawa dissociates ki katote. Ko te aroaro o ng ngota i roto i te ranunga papare tei runga i te kukū o te tote ki roto, me ona tohu o dissociation. Ko te tika hautanga ki te kukū o te waikawa i roto i reira, me te inversely hautanga ki tona ihirangi o Mariao o tenei waikawa te kukū o te H + katote i roto i te pūnaha te moka.

Ko te kupu, Ko te tika hautanga ki te kukū o te tote i roto reira, a inversely hautanga ki te kukū o te turanga te kukū o H + katote i roto i te moka taketake.

I roto i te mahi taiwhanga, te whakamahi i waimeha papare ki uara o te pH mohiotia. Ko te kupu, whakahekea te faaineineraa o waimeha papare i roto i te whakamahi i ngā rongoā o te waikawa ngoikore me ona tai ki te turanga kaha ranei turanga ngoikore, me ona tote ki te waikawa kaha. Na i te huri i te ōwehenga ine o te wāhanga, hangaia waimeha papare ki te pH setpoint. Ētahi feruri e mea nahea te faaineineraa o te otinga.

Hei tauira, he mea e tika ana ki te faaineine i te moka tāpia i te maha ngā uara o pH. I te tīmatanga rite 5m otinga o te waikawa tāpia me te konutai tāpia. Hoki te faaineineraa o te otinga tuatahi tango 50 ml o ia o nga wae. Ma te arata'ihia e te tātai, te kukū o te H + katote i roto i te otinga hua.

Hoki te otinga moka muri tango 80 ml o te otinga waikawa me te 20 ml o te otinga tote rite i mua. He he maha o formulations o ngā waimeha papare whakamahia i roto i te tātari matū me te mahi taiwhanga.

Hoki te āhuatanga monoprotic angamaheni. Ki te hunga matua pā Pūpare - te kaha ki te mau tonu i te tamau o te kukū o te H + ngā katote ka tapiritia i roto i te nui etahi o te otinga moka o te waikawa kaha te turanga kaha ranei. Hei tauira, ki te ki he moka tāpia tāpiri i te nui iti o te pūhaumāota waikawa, pH neke ki te taha ki waikawa e kore e puta, mai ka tauhohe te pūhaumāota waikawa utu whāwehe ki te tote o te waikawa ngoikore. Tauhohenga o te waikawa nekehanga kaha ahei te pH ki te taha waikawa, ka whakakapi i te tote waikawa ngoikore kūpapa. Ko te tohu o te dissociation o te otinga kawehiko ngoikore ki te whakanui ake kukū heke ki te kore, a ka puta te neke pH.
