PH
Ing pH sukad ne ning panga-asidu (kaslam) o panga-alkaline ning metung a solusiun. Deng solusiun king danum o aqueous solutions king pali o temperaturang 25 °C a maki pH a kulang king pitu (7.0) tuturing da lang asidu, kabang alkaline o basic no man detang maki pH a maigit king pitu. Nung saktu yang 7.0 ing kayang pH, tuturing deng 'neutral' king temperaturang 25 °C uling king temperaturang ita, pante ya ing bilang da reng H3O+ karetang OH− king purung danum. Magdependi ya ing pH king aktibidad da reng hydronium ion (H3O+),[1] dapot kareng maina (o dilute) a solusiun, malyari yang gamitan ing molarity ning H3O+ a e midadayu ketang ustung kuenta [2] Ing (H+ pane deng gagamitan a katumbas ning H3O+.) Uling magdependi ya ing pH king aktibidad da reng ion, metung a kaurian (property) a e malaguang sukdan o karkulan ibat king teoria (theoretically), masakit yang pakibaluan ing eksaktung sukad ning pH ning metung a solusiun. keraklan, makukua ya ing sukad ning metung a solusiun kapamilata'ning pamiyanti (comparing) kareng solusiun a e ra pa balu pH karetang balu ra na pH, at ating mapilan a paralan bang marapat iti.
Ing minunang migpakilala king konseptu ning pH ya pin ing chemist ibat Denmark a i S. P. L. Sørensen king Carlsberg Laboratory[3] in 1909. Dakal la reng sasabian dang penibatan ning lagyung pH, kayabe no reng pondus hydrogenii, potentia hydrogenii (Latin),[4] potentiel hydrogène (French), ampong potential of hydrogen (English).[5]
