Quel est le pKa du couple CH3COOH ch3cook ?
Le pKa du couple CH3COOH / CH3COO– vaut 4,8 à 25◦C.
Est-ce que CH3COO est une base forte ?
Acide faible et base faible
Parmi les solutions d'acide faible et de base faible couramment utilisées, on peut citer les deux suivantes : La solution d'acide éthanoïque (aussi appelée acide « acétique ») de formule (\\ce{H3O+_{(aq)}} + \\ce{CH3COO^{-}_{(aq)}}) est une solution d'acide faible.Pourquoi CH3COOH est un acide faible ?
Son acidité caractérisée en solution aqueuse par un pKa = 4,76 vient de sa capacité à perdre temporairement le proton de sa fonction carboxylique, le transformant ainsi en ion acétate CH3COO−.
C'est un acide faible.- Un couple acide‑base s'écrit de la façon suivante : ACIDE / BASE avec l'acide toujours à gauche et la base toujours à droite.
L'acide éthanoïque CH3COOH peut céder un proton H+ et se transformer en CH3COO–, l'ion éthanoate, qui est sa base conjuguée.
Le couple s'écrit CH3COOH/CH3COO–.
