Buffer ke tharollo e ka hanang ho fetoha ha pH ha palo e nyane ea asiti kapa alkali le metsi li eketsoa.Sistimi ea buffer ea pH e bapala karolo ea bohlokoa ho bolokeng boleng bo tloaelehileng ba pH ea lintho tse phelang le tikoloho e tloaelehileng ea fisioloji.Lisele tse ngata li ka sebetsa ka har'a pH e nyane haholo.E hloka ho ba le sistimi ea buffer ho hanela liphetoho tsa pH tse etsahalang nakong ea metabolism.Ho na le litsamaiso tse tharo tsa mantlha tsa pH tse sireletsang 'meleng, ke liprotheine le li-bicarbonate buffer system.Bongata ba sistimi e ngoe le e ngoe ea buffer E fapane ka mefuta e fapaneng ea lisele le litho.
Tšusumetso ea ho thibela tharollo e entsoeng ka acid e fokolang HA le letsoai la eona la NaA holim'a asiti e bakoa ke ho ba teng ha palo e lekaneng ea alkali A- tharollong.Ha tekanyo e itseng ea asiti e matla e eketsoa tharollong ena, li-ion tsa H li sebelisoa ke A-ion:
Ka hona, boleng ba pH ba tharollo bo batla bo sa fetohe;ha palo e itseng ea motheo e matla e eketsoa, asiti e fokolang HA ka tharollo e ja li-OH-ion mme e sitisa phetoho ea pH.
Eketsa palo e nyane ea asiti e matla kapa setsi se matla ho tharollo ea buffer, boleng ba pH ba tharollo bo ke ke ba fetoha haholo, empa haeba palo ea asiti kapa alkali e eketsoa, tharollo ea buffer e tla lahleheloa ke phello ea eona ea ho thibela.Sena se bontša hore boholo ba eona ba buffer bo na le moeli o itseng.
Bokhoni ba ho thibela tharollo bo amana le khokahanyo ea likarolo tse etsang tharollo ea buffer.Tharollo ea buffer e entsoeng ka 0.1mol · L-1HAc le 0.1mol · L-1NaAc e na le matla a mangata a ho thibela ho feta a 0.01mol · L-1HAc le 0.01mol · L-1NaAc.Sena se ka netefatsoa ka lipalo.Leha ho le joalo, mahloriso a likarolo tsa tharollo ea buffer ha ea lokela ho ba kholo haholo, ho seng joalo, tšebelisano pakeng tsa ion e ke ke ea hlokomolohuoa.
