WebAcetic acid (CH 3 COOH) is known to have a pK a of 4.76. Please determine the Ka for acetic acid. Solution Solving for K a algebraically you get the following: pK a = -Log (K a) -pK a = Log (K a) 10 -pKa = K a Using a calculator first enter in the value for the pK a (4.76). … 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.
