WebIn case of acetate ion, its conjugate acid CH3COOH, while definitely a relatively 'weak' acid', isn't weaker than water, so its conjugate base is a weak base. You can calculate the Kb of acetate ion from Kw = Ka*Kb to check this out. It is less compared to, say, ammonia, which is a known weak base. 2 comments ( 22 votes) Upvote Downvote Flag more
