Weak Acid-Base Problems - 1 For each of the following problems, show your work and setup the ICE Table if it is needed. 1) An acid is added to water so that the hydrogen ion concentration is 0.25 M . Calculate the hydroxide ion concentration. [OH - ] = 4.0 x 10 -14 M 2) Calculate the hydrogen ion concentration when in a solution that is 2.0 x 10 -5 M hydroxide ion. [H + ] = 5.0 x 10 -10 M 3) Picric acid, a weak acid, is dissolved in water to prepare a 0.100 M solution. Conductivity measurements at a particular temperature indicate that the picric acid is 82% ionized. Calculate the K a and pK a Ka = 0.37 pK a = 0.43 4) Calculate K a for hydrazoic acid, HN

K a = 1.9 x 10-5 Weak Acid-Base Practice 1-2-5) Laboratory measurements show that a 0.100 M solution of chlorobenzoic acid has a pH of 2.50. Calculate K a K a = 1.1 x 10-4 6) The pH of a 0.011 M acetic acid solution is 2.88. Calculate K a . K a = 1.8 x 10-4 7) Calculate the pH, and the percent ionized, in a 0.100 M solution of the weak acid glycine, for which K a = 1.7 x 10-10 . pH = 5.39 % ionized = 4.1 x 10-3 % 8) Calculate the percent ionized in a 0.0100 M solution of glycine. % ionized = 1.3 x 10-2 %...
