Thus NH … 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.
