WebMar 19, 2024 · Ka = [H3O+][A−] [HA] And for a general base that grabs one proton... A−(aq) + H2O(l) ⇌ HA(aq) +OH−(aq) Kb = [HA][OH−] [A−] Now what if we do this... KaKb = [H3O+][A−] [HA] [HA][OH−] [A−] = [H3O+][OH−] That looks just like Kw. ⇒ Kw = KaKb Therefore, since Kw = 10−14 at 25∘C ... Ka = Kw Kb = 10−14 Kb =??? Answer linkWebThe table lists the K a values and the strength of each acid and base. Strong acids are listed at the top left-hand corner of the table and have Ka values >1 Acids with a K a value less than one are considered weak and get weaker as we move to the bottom of the table.
