r.РArrenhius theory most limited of the three theories since it requires reactions be aqueous and applies only to substances producing H3O+ or OH-.РLiquid ammonia 2 NH3 = NH4+ + NH2- ?Basic substance NaCO3,Na3PO4Р2.2 Bronsted-Lowry TheoryРACID: Substance that can donate proton (H+). ?BASE: Substance that can accept proton (must contain lone pair of electrons).РHCl、HAc、H2O?NH4+、Al(H2O)63+?HSO3РNH3、H2O?Al(H2O)5OH2+?OH、Ac、РBase (proton acceptor)РACID (proton donor)РBronsted/Lowry expands Arrenhius to include any proton transfer (water not requirement).РConjugate acid-base pair? Once an acid transfers its proton it es the conjugate base (CB) and once a base accepts the proton it es the conjugate acid (CA).РACIDРProtonРCBРBaseРProtonРCAРa conjugate acid-base pairРa conjugate acid-base pair
