Check Your Learning Only a small fraction of a weak acid ionizes in aqueous solution. What is the percent ionization of acid in a 0.100-M solution of acetic acid, CH3CO H? acetic CH3 CO2 H(aq) + H20(l) H,0+(aq) + CH 3 CO2-(aq) Ka = 1.8Ã 10-5 (Hint: Determine [CH3 CO21 at equilibrium.) Recall that the percent ionization is the fraction of acetic acid that is ionized Ã100, or [CH3C02-] x100 Answer: percent ionization-1.3%
