Ngā Irahiko: Te Kaha Hiko i roto i te Wairewa
Pendahuluan
He matū te irahiko ka taea te kawe hiko ina rewa i roto i te whakarewa pērā i te wai. Kua waiho tēnei āhuatanga hei kaupapa whakamere i roto i te pūtaiao, inā koa i roto i te matū me te ahupūngao. I roto i tēnei tuhinga, ka matapakihia e mātou he aha ngā irahiko, me pēhea te mahi, ngā momo irahiko, me ō rātou whakamahinga mahi i roto i te oranga o ia rā.
Te Mārama ki ngā Irahiko
Ko ngā irahiko he matū e whaka-ioniti ana i roto i te wairewa, arā, ka wehea hei iona pai, hei iona kino hoki. Ko te waikura wai tētahi o ngā tauira māmā rawa o tēnei āhuatanga, arā, ka wehea ngā ngota wai (H₂O) hei iona hauwai (H⁺) me ngā iona hauwaiwai (OH⁻).
Ngā Ariā Taketake o ngā Irahiko
Ko te mahi a ngā irahiko i runga i te kaupapa o te ionization, arā, te tukanga e wehea ai ētahi ngota hei ion ina rewa ki te wai, ki ētahi atu whakarewa rānei. Ka riro ēnei ion hei kaikawe i te utu hiko, ka taea ai te rere o te hiko mā roto i te otinga.
Ko tētahi tauira māmā noa o te irahiko hiko ko te tote tēpu (NaCl) kua rewa i roto i te wai. Ina rewa te NaCl i roto i te wai, ka wehea hei iona konutai (Na⁺) me ngā iona pūhaumāota (Cl⁻).
Ngā momo irahiko
Ka taea te wehewehe i ngā irahiko ki ngā wāhanga matua e rua: ngā irahiko kaha me ngā irahiko ngoikore.
Irahiko Kaha
Ko ngā irahiko kaha he matū ka tino ionize i roto i te wairewa. Ko ētahi tauira:
1. Ngā waikawa kaha: Waikawa hauwaiora (HCl), waikawa hauota (HNO₃), waikawa whanariki (H₂SO₄)
2. Ngā turanga kaha: Waikawa konutai (NaOH), Waikawa pāhare pākawa (KOH)
3. Tote: Konutai pūhaumāota (NaCl), pāhare pākawa waro (KBr)
He tino teitei te kawe hiko o ngā irahiko kaha nā te mea ka wehea te nuinga o ā rātou ngota hei katote i roto i te wairewa.
Irahiko ngoikore
Ko ngā irahiko ngoikore he matū ka whaka-ionitihia ā-wāhanga noa iho i roto i te wairewa. Ko ētahi tauira:
1. Waikawa ngoikore: Waikawa acetic (CH₃COOH)
2. Pūtake ngoikore: Haukini (NH₃)
He iti ake te kawe hiko o ngā irahiko ngoikore nā te mea ko ētahi o ō rātou ngota ka wehea hei katote i roto i te wairewa.
Te Tūranga o ngā Irahiko i roto i te Tinana Tangata
He mea nui te mahi a ngā irahiko hiko i roto i ngā mahi ā-tinana o te tinana tangata. Ka āwhina rātou ki te whakahaere i te mahi a ngā io me ngā uaua, ki te pupuri i te taurite waikawa-pūtake, me te whakahaere i te nui o te wai i roto i te tinana.
Ngā momo irahiko i roto i te tinana
1. Konutai (Na⁺): He mea nui mō te pupuri i te taurite wai me te mahi a ngā io.
2. Pāhare pākawa (K⁺): He mea nui mō te mahi a te uaua me te io.
3. Konupūmā (Ca²⁺): He mea nui mō te whakaheke uaua me te toto totoka.
4. Konupūmā (Mg²⁺): Whai wāhi ki ngā tauhohenga whākōkī maha.
5. Hauhāora (Cl⁻): Āwhina i te taurite waikawa-pūtake me te whakahaere wai.
6. Phosphate (PO₄³⁻): He mahi nui ki te whakaputa pūngao me te hanganga wheua.
7. Paikāponate (HCO₃⁻): He mea nui mō te taurite o te pH toto.
Te Pānga o te Kore me te Taikaha o te Irahiko
Me pupuri tonu te taurite o ngā irahiko i roto i te tinana. Ka pā mai ngā raruraru hauora maha nā te kore taurite o ngā irahiko, pēnei i:
– Hyponatremia: Ko te kore o te konutai ka pā mai te ngenge, te pōhēhē, tae atu ki ngā haurangi.
– Hyperkalemia: Ka raru pea te manawataki o te ngakau i te nui rawa o te pāhare pāporo.
– Te ngoikore o te pāhare pāporo: Ka ngoikore pea ngā uaua me te ngenge i te korenga o te pāhare pāporo.
Ngā Whakamahinga o ngā Irahiko i roto i te Oranga o Ia Rā
Kāore te whakamahinga o ngā irahiko i te tinana tangata anake. He whānuitia hoki ngā whakamahinga o ngā irahiko i roto i ngā momo hangarau me ngā ahumahi.
Pūhiko
He wāhanga matua ngā irahiko i roto i ngā momo pākahiko maha, tae atu ki ngā pākahiko waikawa-mata e whakamahia whānuitia ana i roto i ngā motuka me ngā pākahiko lithium-ion e whakamahia ana i roto i ngā taputapu hiko pēnei i ngā waea pūkoro me ngā pona. Ko te irahiko i roto i te pākahiko he mea hei kawe i ngā irahiko i waenga i ngā irahiko pai me ngā irahiko kino, e āhei ai te rere o te hiko me te penapena pūngao.
Te hikohiko
Ka whakamahia e te tukanga hikohiko he otinga irahiko hei wehewehe i ngā matū matū mā te whakamahi i te iahiko hiko. Ko ngā tauira tino kitea ko te hikohiko o te wai hei whakaputa i te hauwai me te hāora, te hikohiko rānei o te konutai pūhaumāota hei whakaputa i te hauwai konutai me te haurore.
Te Maimoatanga Wai
Ka whakamahia hoki ngā irahiko i roto i te maimoatanga wai, tae atu ki ngā tukanga tango tote hei huri i te wai moana hei wai māori inu. He maha ngā wā ka whakamahia he kiriuhi e tuku ana i ētahi iona anake kia puta, kia wehea ai te tote mai i te wai.
Whakaora wai
Ko ngā inu whakaora wai, e whakamahia ana e ngā kaitākaro me te hunga e mate ana, kei roto ngā electrolytes hei āwhina i te whakahoki mai i te taurite katote o te tinana me te ārai i te matewai. Ko te tikanga kei roto i ēnei hua te konutai, te pāhare pāporo, te konupūmā, me te konupora.
Whakamutunga
He mea nui ngā irahiko hiko e whai wāhi nui ana ki ō tātou oranga, i roto i ngā mahi ā-tinana o te tinana tangata me ngā mahi hangarau rerekē. Mā te mārama ki te mahi a ngā irahiko hiko me ō rātou mahi nui ka āwhina i a tātou ki te mārama ki te pānga o aua mea ki te hauora me te whanaketanga hangarau. Mai i te pupuri i te taurite o te tinana ki te whakakaha i ngā taputapu hiko e whakamahia ana e tātou i ia rā, ko ngā irahiko hiko ngā kaha hiko i roto i te wairewa kaua e warewaretia.
