In the presence of an acid, it acts as aproton acceptor; in the presence of a base, it acts as a proton donor. In fact, one watermolecule can donate a proton to another water molecule:Ge H Some Theghtw ECriggWIO at lH2O(1)+H2O(1)ОН (ад) +H;O* (aq)asa lewio ed er raalo od O ova A. uriel .l IE+:ö-H:ö-HF ngSeger+:O:+Н-ӧ—НIR Pd te Pekes s reton-TrawerHHH.H[16.12]677+indsyAcidBaseWe call this process the autoionization of water.Because the forward and reverse reactions in Equation 16.12 are extremelyrapid, no water molecule remains ionized for long. At room temperature only abouttwo out of every 10' water molecules are ionized at any given instant. Thus, purewater consists almost entirely of H2O molecules and is an extremely poor conductorof electricity. Nevertheless, the autoionization of water is very important, as we wille16.3 The Autoionization of Watert ren lade Ead hesa pWhe ld w eupl . delg Msoon see.Th.paLig6783AUG8.étv AP00||| PreviewFileEditViewGoToolsWindowHelpSun Aug 8 5:50 PMbartleby.com(1) ĆTheodore E.
