Webb18 juni 2024 · What is considered a strong Ka? In the formulas, A stands for acid and B for base. A large Ka value indicates a strong acid because it means the acid is largely dissociated into its ions. A small Ka value means little of the acid dissociates, so you have a weak acid. The Ka value for most weak acids ranges from 10-2 to 10-14. WebbIn 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 greene\u0027s pub woburn ma
