WebThe acid–base strength of a molecule depends strongly on its structure. The weaker the A–H or B–H+ bond, the more likely it is to dissociate to form an H + ion. In addition, any factor that stabilizes the lone pair on the conjugate base favors the dissociation of H +, making the conjugate acid a stronger acid. citizenship form australia
