Unformatted text preview: than the pKa of the most acidic proton. This ensures that the protons have not dissociated because the pKa of the most acidic (most likely to dissociated) proton has not yet been reached. In the case of the graph to the left, the first pKa (most acidic) is 2.2. In order to ensure the acid is fully protonated, the solution pH must not be higher than 2.2. This ensures that the protons that will dissociate at 2.2 will still be on the molecule. 3. a. b....
