BICINE is a compound that contains a tertiary amino group. You have 0.5 L of 0.05 M BICINE with its tertiary amine in the unprotonated form. How much 0.2 M HCl or 0.2 M NaOH must be added in order to create a BICINE buffer solution pH = 7.5. (pKa = 8.3)
Two different solutions were prepared. Solution A was prepared by dissolving sodium acetate in methanol and solution B was prepared by adding potassium methoxide to acetic acid.
