I-Buffer sisisombululo esinokumelana nokutshintsha kwe-pH xa isixa esincinci se-asidi okanye i-alkali kunye namanzi zongezwa.Inkqubo yesithinteli se-pH idlala indima ebalulekileyo ekugcineni ixabiso le-pH lesiqhelo lezinto eziphilileyo kunye nemekobume yefiziyoloji eqhelekileyo.Uninzi lweeseli zinokusebenza kuphela kuluhlu lwe-pH emxinwa kakhulu.Kufuneka ibe nenkqubo ye-buffer ukuxhathisa utshintsho lwe-pH olwenzeka ngexesha le-metabolism.Kukho iinkqubo ezintathu eziphambili zesithinteli se-pH kwizinto eziphilayo, ziinkqubo zeprotheyini kunye ne-bicarbonate buffer.Isixa senkqubo ye-buffer nganye Yahlukile kwiintlobo ezahlukeneyo zeeseli kunye namalungu.
Umphumo we-buffering wesisombululo se-buffer esiqulunqwe yi-asidi ebuthakathaka HA kunye netyuwa yayo i-NaA kwi-asidi ngenxa yobukho bexabiso elaneleyo le-alkali A-kwisisombululo.Xa isixa esithile seasidi eyomeleleyo yongezwa kwesi sisombululo, ii-ion zeH zityiwa zii-ayoni:
Ngoko ke, ixabiso le-pH lesisombululo liphantse lingatshintshi;xa umlinganiselo othile wesiseko esinamandla songezwa, i-asidi ebuthakathaka HA kwisisombululo idla i-OH-ion kwaye ithintela utshintsho lwe-pH.
Yongeza inani elincinci le-asidi eqinile okanye isiseko esomeleleyo kwisisombululo se-buffer, ixabiso le-pH lesisombululo aliyi kutshintsha kakhulu, kodwa ukuba inani le-asidi okanye i-alkali yongezwa, isisombululo se-buffer siya kulahlekelwa yi-buffering effect.Oku kubonisa ukuba umthamo wayo wesithinteli unomda othile.
Umthamo webuffer yesisombululo se-buffer unxulumene noxinaniso lwamalungu enza isisombululo se-buffer.Isisombululo se-buffer esihlanganiswe ne-0.1mol · L-1HAc kunye ne-0.1mol · L-1NaAc inomthamo omkhulu we-buffer kunesisombululo se-buffer se-0.01mol · L-1HAc kunye ne-0.01mol · L-1NaAc.Oku kunokuqinisekiswa ngokubala.Nangona kunjalo, ukuxinwa kwamacandelo esisombululo se-buffer akufanele kube kukhulu kakhulu, ngaphandle koko, intsebenziswano phakathi kweeoni ayikwazi ukuhoywa.
