WebFeb 19, 2016 · Ka = (A-)* (H3O+)/ (HA) And Kb = (HB+)* (OH-)/ (B) If it were the same reaction (with an acid and its conjugate base, it would be this way: Ka = (A-)* (H3O+)/ (HA) And Kb = (HA)* (OH-)/ (A-) Clearly, ka =/ 1/Kb : one has H3O+ and the other has OH- (the … WebSep 5, 2024 · A lower pKa means the Ka value is higher and a higher Ka value means the acid dissociates more readily because it has a larger concentration of Hydronium ions (H3O+). If you have a low pKb, then your Kb value is high. 10^-pKb = Kb. That means …

WebThe 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. WebApr 28, 2024 · This is because a weak base (low Kb value) will generate a strong conjugate acid (high Ka value) (remember that K a K b =Kw for a conjugate acid-base pair). Examples for cations: Cation generated from a strong base: example Na + from NaOH NaOH (aq) → Na+(aq) + HO - (aq) strong base (high Kb) weak conjugate acid (low Ka) c# how to convert byte to string
