Aooa? Pāʻoihana: e hoomakaukau ai a me ka hoʻohana '

Iauae-oaie aooa - ia pāʻoihana i loaʻa ka buffering nenoaiu. Aooa? Nenoai kapa ukuhiia i loko i ka haku mele he i ke koho 'ia laupaʻi lākiō nāwaliwali nāʻakika a me kā lākou mau paʻakai me ka mau kumu ikaika a nawaliwali kumu a me kā lākou mau paʻakai i nāʻakika ikaika. Oia pāʻoihana i ka hale lio lehulehu o ka H + Ion ma'ākilikai nāu'ūheheʻe (ka wai) a ohui ia ia i kekahi nui o nāʻakika a me kumu ikaika.

Aooa? Pāʻoihana i loko o nā wai o nā moana, lepo pāʻoihana a me ka noho ana meaola. Mau nenoai hana kumu hoʻohālikelike a hana i kākoʻoʻeleu naoh meakino ma ka hoakaka pono no ka holomua hanana o metabolic reactions waiwai. Aooa? Pāʻoihana e hoʻolaha i loko oʻakika a me ka walaʻauʻana. An kumu hiki mua e'ākeka aooa?'ōnaehana, ka lua -'amoniuma. Hoomaopopo maoli a me kaʻimi hoʻopunipuni iauae-oaie aooa. A maoli aooa? Pāʻoihana o ke koko i loaʻa ka hydrocarbonate, posapahate, kumuʻiʻo, hemoglobin a me kaʻakika aooa? Nenoaiu. ʻimi hoʻopunipuni aooa? I e'ākeka aooa, oia hoi o CH3COOH.

Hiʻona o na 'ole a me kaʻano papa hana o ka hana o ka aooa? Nenoai ke kumu hoohalike o ka'ākeka aooa?'ōnaehana mākou noonoo:'ākekaʻakika / paʻakai'ākeka. Ma ke koʻana koko meakino i aooa?'ōnaehana eiiiiiaiou i hoolilo electrolytic dissociation. Paʻakai'ākeka like me ka paakai o ka palupaluʻakika, a me ka ikaika kumu loa dissociates i Ion. Ke alo aku o anions i loko o ka aooa? Ukuhiia hilinaʻi nui ma luna o ka lehulehu o ka paʻakai ma loko a me kona degere o ka dissociation. I ka lehulehu o ka H + Ion ma ke aooa?'ōnaehana mea pololei hapaʻauhau i ka lehulehu o kaʻakika i loko o laila, a inversely hapaʻauhau i kona maʻiʻo o ka paʻakai o kēiaʻakika.

Ke'ī mai, i ka lehulehu o H + Ion ma ke kumu o aooa? Mea pololei hapaʻauhau i ka lehulehu o ka paakai i loko o laila, a inversely hapaʻauhau i ka lehulehu o ka waihona ipu.

Ma keʻena hoʻokolohua hana, hoʻohana aooa? Pāʻoihana me ka ikeia aiee o ka pH. Ke'ōlelo mai, no ka makaukau o ka aooa? Pāʻoihana ua lawe mai ma ka hoʻohana pāʻoihana o ka palupaluʻakika a me kona paʻakai me ka waihona ikaika a nawaliwali kumu a me kona paʻakai me kaʻakika ikaika. A laila, ma ka hoololi ana i ka laupaʻi lākiō o na eiiiiiaiou, aooa? Pāʻoihana ua hanaʻia me ka setpoint pH. Kekahi kahaha no ana i ka makaukau ana o ka pāʻoihana.

No ka laʻana, ka mea, Ua pono, e hoomakaukau i'ākeka aooa? Ma kekahi mau aiee o ka pH. Initially hoomakaukau 5M pāʻoihana o'ākekaʻakika a me ka paʻakai'ākeka. No ka makaukau o ka pāʻoihana mua lawe 50 ml o kela a me keia o na eiiiiiaiou. Alakaʻi ma ka haʻilula, i ka lehulehu o ka H + Ion ma ke kūpono pāʻoihana.

No ka mea e hiki mai ana aooa? Pāʻoihana lawe 80 ml o kaʻakika pāʻoihana a me 20 ml o ka paakai pāʻoihana hoʻomākaukau mua ai. Aia nō i ka nui o nā mea haʻilula keimikala o kekahi mau oaie aooa? Pāʻoihana i hoʻohana ma Nine Inch Ka Ikepili a me ka keʻena hoʻokolohua hana.

No ka typical iauae-waiwai. I ka poe kuhikuhi pili Buffering - ka hiki, e malama i ke kūpaʻa o ka lehulehu o ka H + Ion ka wā i hoʻohuiʻia i loko o ka kekahi nui o aooa? Pāʻoihana o kaʻakika ikaika a me ka ikaika kumu. No ka laʻana, ina he'ākeka aooa? E hookui i ka uuku nui o kaʻakika koloriside, pH naeaeaa i kaʻaoʻaoʻakika 'aʻole i ana, mahope mai o kaʻakika koloriside e pane koke mail decomposition me ka paakai o ka nawaliwaliʻakika. Naoh o ka ikaikaʻakika hiki ia oe neʻe aku i ka pH a hiki i kaʻaoʻaoʻakika, a UAIAaIN ma ka'ākilikai nawaliwaliʻakika paʻakai. Ke degere o ka dissociation o ka nawaliwali electrolyte pāʻoihana me ka hoʻoulu lehulehu emi i 'Aʻohe, a me ka pH naeaeaa ia lŘlŘ.
