Conjugate acid of a weak base

WebThe conjugate base of a very weak acid is stronger than the conjugate base of a strong acid. A strong acid is composed of a proton and an anion that have a very strong attraction for one another. A strong acid has a strong conjugate base. A weak base is composed of a cation and an anion with a very weak attraction between them. WebAccording to the Henderson-Hasselbalch approximation (Equation 7.1.20 ), the pH of a solution that contains both a weak acid and its conjugate base is pH = pKa + log([A −] / [HA]). A Inserting the given values into the …
