WebThe value of the equilibrium constant is given by. Kb = [BH+][OH−] B. The greater the value of Kb, the stronger the base. For most weak acids, Kb ranges from 10−2 to 10−13. pKb = − logKb. For most weak acids, pKa ranges from 2 to 13. The smaller the value of pKb , the stronger the base. Here's a video on pKa and pKb.

WebNov 11, 2024 · pKa Definition pK a is the negative base-10 logarithm of the acid dissociation constant (K a) of a solution. pKa = -log 10 K a The lower the pKa value, the stronger the acid. For example, the pKa of acetic acid is 4.8, while the pKa of lactic acid is 3.8. Using the pKa values, one can see lactic acid is a stronger acid than acetic acid.
