In other words, select a 'l' next to the solution that will have the lowest pH, a 2 next to the … WebH-O-Y acids (Y is usually a Group 17 atom) exhibit greater dissociation if the Y atom is more electronegative. This is because the electronegative Y will pull electrons towards itself and reduce the electron density around the H-O bond, thereby weakening the bond and allowing H+ to dissociate.

WebAcid strength is determined by the amount of that acid that actually ionizes. Acids are molecular covalent compounds which you don't expect to ionize (release an #H^+# and leave behind the conjugate base, or #Cl^-# for example).. The strongest acids ionize 100%. There are 6 that most consider to be the "STRONG" acids: HCl, HI, HBr, HNO_3 #, …
