Unformatted text preview: (K a ) for HClO 2 in water is 0.011. Name: 2 I.2 (8 points) The pH of a 0.13 M CH 3 CO 2 H solution is 2.82. What is the equilibrium constant (K a ) for CH 3 CO 2 H? I.3 (2 points) The K a for CH 3 CH 2 OH is 1.0 x 10-17 . Is CH 3 CO 2 H or CH 3 CH 2 OH a stronger acid? (If youre interested, the difference in acidity can be rationalized by resonance stabilization of the anion formed. Can you draw this stabilization?)...
