WebHydrochloric acid (HCl), acetic acid (CH 3 CO 2 H or HOAc), nitric acid (HNO 3 ), and benzoic acid (C 6 H 5 CO 2 H) are all monoprotic acids. Several important acids can be classified as polyprotic acids, which can lose … 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. can you spread staph infection
