Te Mahi a ngā Otinga Pūwero i te Ao
Pendahuluan
Ko te otinga ārai, e mōhiotia ana ko te otinga ārai, he otinga e pupuri ana i te pH pumau ahakoa ka tāpirihia he waikawa, he kawa rānei. He mea nui tēnei āhuatanga i roto i ngā tukanga koiora, matū, me ngā tukanga ahumahi maha. I roto i te oranga o ia rā, he mea nui, he rerekē hoki ngā mahi a ngā otinga ārai, mai i te tautoko i ngā tauhohenga matū i roto i te tinana ki te pupuri i te kounga o ngā hua ahumahi.
Te Mātāpono Mahi o te Otinga Pūwero
Ko te otinga pākawa he mea hanga mai i te waikawa ngoikore me tōna turanga honohono, he turanga ngoikore rānei me tōna waikawa honohono. Ka mahi ngā otinga pākawa mā te tauhohenga matū e uru ana te waikawa ngoikore me tōna turanga honohono, te ritenga kē rānei, kia iti ai ngā huringa o te pH ina tāpirihia he waikawa, he turanga rānei.
I roto i ngā taipitopito, ka mahi te otinga parepare mā te tango i ngā iona H+ mēnā he pūtake tāpiri, mā te tuku rānei i ngā iona H+ mēnā he waikawa tāpiri. Hei tauira, i roto i te otinga parepare kei roto ko te waikawa acetic (CH3COOH) me tōna pūtake honohono konutai acetate (CH3COONa), ina tāpirihia he waikawa kaha pērā i te HCl, ka tauhohe ngā iona H+ mai i te HCl ki ngā iona acetate (CH3COO-) mai i te konutai acetate hei hanga waikawa acetic, kia mau tonu ai te pH o te otinga. I tetahi atu taha, mēnā ka tāpirihia he pūtake kaha pērā i te NaOH, ka tauhohe ngā iona OH- mai i te NaOH ki ngā iona H+ mai i te waikawa acetic hei hanga wai, ā, ka mau tonu te pH pumau.
Ngā Mahi a ngā Otinga Pūwero i te Oranga o Ia Rā
1. Ngā Pūnaha Koiora me te Hauora
Ko tētahi o ngā mahi tino nui a ngā otinga parepare kei roto i ngā pūnaha koiora. I roto i te tinana tangata, he maha ngā momo ngā tauhohenga matū koiora Ko te pH pumau te mea e whakawhirinaki ana ki te ora katoa. Ko tētahi o ngā tauira pai ko te toto tangata, he pūnaha tiaki tuatahi kei roto ko te waikawa waro (H2CO3) me te paikāponate (HCO3-). Mā tēnei pūnaha ka mau tonu te pH o te toto tangata i waenga i te 7,35 me te 7,45. Mā te kore taurite o te pH toto ka arahi pea ki ngā āhuatanga kino pēnei i te waikawa waikawa, te mate pāwera rānei, ka mate pea.
Haunga te toto, he mea nui anō hoki ngā pūnaha ārai i te pupuri i te pH o ngā wai pūtau me ngā wai i waenga i ngā pūtau. Ko ngā tauhohenga whākōkī i roto i te tinana e hiahia ana ki tētahi taiao pH motuhake kia pai ai te mahi me te whai huatanga.
2. Ahumahi Kai me te Inu
I roto i te umanga kai me te inu, ka whakamahia ngā otinga pūmau hei whakahaere i te reka o te hua, te pumau, me te kounga. Hei tauira, ka whakamahia te konutai citrate i roto i ngā inu hei pupuri i te taurite pH me te ārai i ngā huringa reka nui. I roto i te umanga miraka, mā te tāpiri i ngā pūmau hei pupuri i tētahi pH motuhake ka āwhina i ngā tukanga whakapūmautanga e whakahaeretia ana, ā, ka puta he hua kounga teitei.
3. Ahuwhenua
I roto i te ahuwhenua, e hiahiatia ana ngā wai whakapūmau hei whakarite kia noho tonu te pH o te oneone i roto i ngā rohe tino pai mō te tipu o ngā tipu. Ko te nuinga o ngā tipu e hiahia ana ki tētahi awhe pH oneone motuhake kia pai ai te mimiti o ngā matūkai. Mā te whakamahinga o ngā wai whakapūmau i roto i ngā tongi ka āwhina i te pumau o te pH o te oneone, ka whakapai ake i te kounga me te hua o te hua.
4. Taiwhanga me te Rangahau
He mea nui anō hoki ngā otinga pūwero i roto i ngā taiao taiwhanga. I te wā e whakahaerehia ana ngā whakamātautau matū, koiora rānei, he mea nui te pumau o te pH ki te whiwhi hua tika me te pono. He maha ngā tikanga taiwhanga, pērā i te electrophoresis gel, te PCR (Polymerase Chain Reaction), me ngā momo tikanga tātari, e hiahia ana ki ngā otinga pūwero motuhake hei arotau i ngā tauhohenga.
5. Ngā Mea Whakapaipai me ngā Rongoā
I roto i ngā ahumahi whakapaipai me te rongoā, me whakahaere te pH o te hua kia pai ai te haumaru me te whai huatanga. Ko ngā hua tiaki kiri, pērā i ngā kirīmi kanohi, i ngā shampoo rānei, me whai pH e ōrite ana ki te pH tūturu o te kiri kia kore ai e riri. Ka whakamahia ngā otinga whakapūmau hei whakarite tika i te pH o te hua, kia pai ai te whakamahi, kia haumaru ai hoki.
6. Te Maimoatanga Wai
Ka whakamahia hoki ngā wai whakapūmau i roto i te maimoatanga wai mō ngā whakamahinga kāinga me ngā ahumahi. Me whai pH motuhake te wai inu kia haumaru ai te inu. Waihoki, me tukatuka te wai para i mua i te tukunga ki te taiao hei ārai i te kino o te rauropi. Mā te whakamahinga o ngā matū whakapūmau i roto i te maimoatanga wai ka āwhina i te pupuri i te pH o te wai ki roto i ngā rohe haumaru.
Whakamutunga
He mea nui te mahi a ngā wairewa whakapūmau i roto i ngā āhuatanga maha o te oranga. Nā te kaha ki te pupuri i te pH pumau, he mea nui ēnei ki ngā pūnaha koiora, ki te umanga kai me te inu, ki te ahuwhenua, ki ngā taiwhanga rangahau, ki ngā umanga whakapaipai me te rongoā, me te maimoatanga wai. Ki te kore ngā wairewa whakapūmau, he maha ngā tukanga e whakawhirinaki ana ki te pumau o te pH e kore e mahi pai, ka pā kino pea ki te hauora, te kounga o te hua, me te taiao.
Nō reira, ko te mārama me te whakamahi i ngā mahi a ngā otinga ārai i roto i te oranga o ia rā he taahiraa nui ki te tautoko i ngā momo mara e whai wāhi ana ki te oranga o te tangata me te oranga tonutanga o te taiao. Kia maioha tātou ki ngā painga o ngā otinga ārai mō te pai whānui, ā, kia haere tonu tā tātou tūhuratanga.
