The same trend applies to the VIA hydrides. Their bond strength has this trend. H 2 O >> H 2 S > H 2 Se > H 2 Te The acid strength is the reverse trend. H 2 O << H 2 S < H 2 Se < H 2 Te Strengths of Acids The acid leveling effect masks the differences in acid strength of the hydrohalic acids. The strongest acid that can exist in water is H 3 O + . Acids that are stronger than H 3 O + merely react with water to produce H 3 O + . Consequently all strong soluble acids have the same strength in water. HI + H 2 O H 3 O + + I - essentially 100% Strengths of Acids HBr, which should be a weaker acid, has the same strength in water as HI. HBr + H

Unformatted text preview: 2 O → H 3 O + + Br-essentially 100% Acid strength differences for strong acids can only be distinguished in nonaqueous solutions like acetic acid, acetone, etc. Strengths of Acids Using our knowledge of BrØnsted-Lowry theory, it is possible to construct a relative ranking of acid and base strengths (and their conjugate partners.) Strengths of Acids It is possible to do this for essentially every acid and base (and their partners). Strengths of Acids The strongest acid that can exist in water is H 3 O + . HCl + H 2 O → H 3 O + + Cl-...
