Buffer ndi yankho lomwe lingathe kukana kusintha kwa pH pamene asidi pang'ono kapena alkali ndi madzi awonjezeredwa.Dongosolo la pH buffer limakhala ndi gawo lofunikira pakusunga kufunikira kwa pH yazamoyo komanso chilengedwe chachilengedwe.Maselo ambiri amatha kugwira ntchito pa pH yochepa kwambiri.Iyenera kukhala ndi buffer system kuti ikane kusintha kwa pH komwe kumachitika panthawi ya metabolism.Pali njira zitatu zazikuluzikulu zotchingira pH m'thupi, ndi ma protein ndi bicarbonate buffer system.Kuchuluka kwa dongosolo lililonse la buffer Ndikosiyana mumitundu yosiyanasiyana ya ma cell ndi ziwalo.
Kuwonongeka kwa njira ya bafa yopangidwa ndi asidi wofooka HA ndi mchere wake NaA pa asidi ndi chifukwa cha kupezeka kwa alkali wokwanira A- mu yankho.Pamene asidi amphamvu awonjezeredwa ku yankho ili, ma ions a H amadyedwa ndi ma ions:
Choncho, pH mtengo wa yankho ndi pafupifupi wosasintha;pamene kuchuluka kwa maziko amphamvu akuwonjezeredwa, asidi ofooka HA mu yankho amadya ma OH- ions ndipo amalepheretsa kusintha kwa pH.
Onjezerani pang'ono asidi amphamvu kapena maziko amphamvu ku yankho la bafa, mtengo wa pH wa yankho sudzasintha kwambiri, koma ngati kuchuluka kwa asidi kapena alkali kuwonjezeredwa, yankho la buffer lidzataya mphamvu yake.Izi zikuwonetsa kuti buffer yake ili ndi malire.
Kuchuluka kwa buffer kwa yankho la bafa kumakhudzana ndi kuchuluka kwa zigawo zomwe zimapanga yankho la bafa.Yankho la buffer lopangidwa ndi 0.1mol · L-1HAc ndi 0.1mol · L-1NaAc lili ndi mphamvu yochuluka kwambiri kuposa yankho la buffer la 0.01mol · L-1HAc ndi 0.01mol · L-1NaAc.Izi zikhoza kutsimikiziridwa ndi kuwerengera.Komabe, kuchuluka kwa zigawo za yankho la buffer sikuyenera kukhala kwakukulu, apo ayi, kuyanjana pakati pa ayoni sikunganyalanyazidwe.
