Unformatted text preview: 0.1 Molar solution of acetic acid. Acid : HA HA <_> H+ + A-0.1 O O I-x +x +X C .1 – x x x E Ka = [H+][A-] / [HA] 1.8E-5 = Ka = (x^2) / (0.1 – x) Since Ka is small & the conc. Is reasonable that … .1 – x ~ = .1 Ka = x^2 / .1 X = 0.00134 M = H+-log (.00134) = 2.873 Can I use the assumption? If Ka is small … <10E-4 AND the conc. Is reasonable … >0.05 M What is the percent ionization of 0.10 M acetic acid solution?...
