CHEM 1131 7/17/06 Concept Tests for Wednesday July 12, 2006 1. Rank the following compounds in order of increasing acidity ( i.e. acid strength). Carbonic acid (H 2 CO 3 ), K a = 3.98 x 10 -7 Benzene (C 6 H 6 ), K a = 1.0 x 10 -43 Isopropanol ((CH 3 ) 2 CHOH), K a = 1.0 x 10 -17 Water, K a = 1.99 x 10 -16 Bicarbonate (HCO 3 - ), K a = 6.31 x 10 -11 Glycine, K a = 2.51 x 10 -10 Higher K a value = more acidic compound benzene < isopropanol < water < bicarbonate < glycine < carbonic acid
