Equilibria of Weak Bases, K b - Purdue University

WebTranscript. In a weak base-strong acid titration, the acid and base will react to form an acidic solution. A conjugate acid will be produced during the titration, which then reacts with water to form hydronium ions. This results in a solution with a pH lower than 7. An example of this is the titration of hydrochloric acid (strong acid) into ... WebThe higher the Ka and Kb values, the stronger the acid or base. The higher the Ka and Kb values, the weaker the acid or base. When Ka values equal Kb values, the acid is strong. people magazine awards ticketsWebThe 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. tofu hong
