I-Buffer yisisombululo esingamelana noshintsho lwe-pH lapho inani elincane le-asidi noma i-alkali namanzi kwengezwa.Uhlelo lwe-pH buffer ludlala indima ebalulekile ekugcineni inani le-pH elivamile lezinto eziphilayo kanye nemvelo evamile yokuphila.Amaseli amaningi angasebenza kuphela ebangeni le-pH elincane kakhulu.Idinga ukuba nesistimu ye-buffer ukumelana nezinguquko ze-pH ezenzeka ngesikhathi se-metabolism.Kunezinhlelo ezintathu ezibalulekile ze-pH buffer entweni ephilayo, zingamaprotheni kanye nezinhlelo ze-bicarbonate buffer.Inani lesistimu ye-buffer ngayinye Ihlukile ezinhlotsheni ezahlukahlukene zamaseli nezitho.
Umphumela wokubhafa wesixazululo sebhafa esakhiwe i-asidi ebuthakathaka engu-HA kanye nosawoti wayo i-NaA ku-asidi kungenxa yokuba khona kwenani elanele le-alkali A- esixazululweni.Lapho inani elithile le-asidi eqinile lengezwa kulesi sixazululo, ama-H ions asetshenziswa ama-A-ion:
Ngakho-ke, inani le-pH lesixazululo licishe lingashintshiwe;lapho inani elithile lesisekelo esiqinile lengezwa, i-asidi ebuthakathaka i-HA esixazululweni idla ama-OH- ions futhi ivimbela ukuguqulwa kwe-pH.
Engeza inani elincane le-asidi eqinile noma isisekelo esiqinile kusixazululo se-buffer, inani le-pH lesixazululo ngeke lishintshe kakhulu, kodwa uma inani le-asidi noma i-alkali lengezwa, isisombululo se-buffer sizolahlekelwa umphumela waso wokubhafa.Lokhu kubonisa ukuthi umthamo wayo webhafa unomkhawulo othile.
Umthamo wokubhafa wesixazululo sebhafa uhlobene nokuhlangana kwezingxenye ezenza isisombululo sebhafa.Isixazululo sebhafa esakhiwe ngo-0.1mol·L-1HAc kanye no-0.1mol·L-1NaAc sinamandla amakhulu okubhafa kunesixazululo sebhafa esingu-0.01mol·L-1HAc no-0.01mol·L-1NaAc.Lokhu kungaqinisekiswa ngokubala.Kodwa-ke, ukugxila kwezingxenye zesixazululo sebhafa akumele kube kukhulu kakhulu, ngaphandle kwalokho, ukusebenzisana phakathi kwama-ion akunakuzitshwa.
