CHE 107 ch. 15

exam material

Acids sour taste can dissolve many metals neutralize bases
bases bitter slippery neutralize acids
Arrhenius acid and base Bronsted-Lowry difinition is broader conjugate acid-base pairs differ by a single H+
Water is amphoteric
at 25 celcius, Kw = 1.0 x 10-14 Kw=[H+][OH-]
pH=-log[H+] pOH=-log[OH-] pH+pOH=14
percent ionization of weak acids %ionization=[H3O+]equil/[HA]initial *100
strong and weak acids strong acid completely dissociates high concentration of H+ -equilibrium of weak acid dissociation is diriven to the left (HA formation) due of Le Chatelier's priciple
mixture of weak acids multiple reactions -find the storongest of the acids (highest Ka value) -do the Ka calculation as if it was the only acid
