ʻO ka Buffer kahi hopena hiki ke pale aku i nā loli pH ke hoʻohui ʻia kahi wahi liʻiliʻi o ka waikawa a i ʻole ka alkali a me ka wai.He kuleana koʻikoʻi ka ʻōnaehana pH buffer i ka mālama ʻana i ka waiwai pH maʻamau o nā mea ola a me ke ʻano physiological maʻamau.Hiki i ka hapa nui o nā pūnaewele ke hana ma kahi ākea pH haiki loa.Pono e loaʻa kahi ʻōnaehana pale e pale aku i nā hoʻololi pH i ka wā o ka metabolism.ʻEkolu mau ʻōnaehana pale pH koʻikoʻi i loko o ke kino, ʻo ia ka protein a me ka bicarbonate buffer system.ʻO ka nui o kēlā me kēia ʻōnaehana pale He ʻokoʻa ia i nā ʻano ʻano o nā cell a me nā ʻāpana.
ʻO ka hopena hoʻopaʻa ʻana o ka wai hoʻopaʻa i haku ʻia me ka ʻakika nāwaliwali HA a me kona paʻakai NaA ma ka ʻakika ma muli o ka loaʻa ʻana o ka nui o ka alkali A- i loko o ka hopena.Ke hoʻohui ʻia kekahi nui o ka ʻakika ikaika i kēia hoʻonā, hoʻopau ʻia nā iona H e nā A- ion:
No laila, ʻaneʻane hoʻololi ʻole ka waiwai pH o ka hopena;ke hoʻohui ʻia kekahi nui o ke kumu ikaika, ʻo ka ʻakika nāwaliwali HA i loko o ka hoʻonā e hoʻopau i nā OH- a keʻakeʻa i ka hoʻololi ʻana o ka pH.
E hoʻohui i kahi ʻakika ikaika a i ʻole ke kumu ikaika i ka solution buffer, ʻaʻole e loli nui ka pH waiwai o ka hopena, akā inā hoʻohui ʻia ka nui o ka waikawa a i ʻole ka alkali, e nalowale ka hopena paʻa i ka hopena buffering.Hōʻike kēia i kona hiki ke pale i kekahi palena.
ʻO ka hiki ke hoʻopaʻa ʻia o kahi hoʻonā paʻa e pili ana i ka neʻe ʻana o nā ʻāpana i hana i ka hopena buffer.ʻOi aku ka nui o ka hiki ke hoʻopaʻa ʻia ma mua o ka hoʻonā paʻa o 0.01mol·L-1HAc a me 0.1mol·L-1NaAc a me 0.1mol·L-1NaAc.Hiki ke hōʻoia i kēia ma ka helu ʻana.Eia nō naʻe, ʻaʻole pono ka nui o ka ʻike ʻana o nā ʻāpana o ka hopena buffer, i ʻole, ʻaʻole hiki ke mālama ʻia ka pilina ma waena o nā ion.
