a) Draw precisely the titration curve for the addition of NaOH to 0.01 M solution of acetic acid (CH3COOH). Your solution should include the following:
• calculation and tabulation of at least 10 values of pH versus f; and,
• a diagram of the titration curve underneath its accompanying pC-pH diagram.
b) For a dilute acetic acid solution: 1. develop the appropriate ionization fraction equations; and, 2. draw the species distribution plot (α0 and α1 vs pH).
