The acid or the conjugate base will predominate at 3.0 pH . Introduction: Strong acids readily dissociate into its ions when they are dissolved in water, whereas weak acid partially dissociates into its ions when they are dissolved in water. The dissociation of acid yield conjugate base and hydronium ion. At equilibrium, the concentration of acid and its conjugate base is same. Below p K a value of acid, acidic form predominates and above that conjugate form predominates.
