WebThe presence of much water causes the red colour of a faintly acid solution of methyl orange to become yellow, probably due to hydrolytic dissociation. The indicator solution generally used is prepared by dissolving 0.1gm in 100cc of distilled water. One drop of this solution is used for each 20cc of the solution to be titrated. WebMar 14, 2024 · The protonation of a weak acid/base is the gain or loss of a proton to form a conjugate acid or base. So percent protonation measures how much of the initial compound reacted to form its conjugate. For a weak acid, you divide the H+ M by the initial concentration of HA and multiply by 100. For a weak base, you divide the OH- M by the …

[1] [2] The species formed is the conjugate base of that acid. The complementary process, when a proton is added (transferred) to a Brønsted–Lowry base, is protonation (or hydronation).
