The 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. WebJan 31, 2024 · All acids of the generic formula HA have pKa. HA − ⇀ ↽ − H + + A −. The equilibrium constant for this simplified reaction can be written as. Keq = [H +][A −] HA Ka = [HA]Keq = [H +][A −] pKa = − logKa. The pK a becomes a simple measure of the strength of an acid. The stronger the acid, the larger the K a and the smaller the pK a. ea college football WebWeak acid pka 8.3. Phenytoin. Weak acid pka 8.3. Phenobarbital. Weak acid pka 7.4. Pentobarbital.
