Recall that ammonia (NH 3) acts as a base because the nitrogen atom has a lone pair of electrons that can accept a proton. 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. ilahia college of engineering technology
