WebLooking at Table 5.2. 1, you see that the pK a of carboxylic acids are in the 4-5 range, the pK a of sulfuric acid is –10, and the pK a of water is 14. Alkenes and alkanes, which are not acidic at all, have pK a values above 30. The lower the pKa value, the stronger the acid. Table 5.2. 1: Representative acid constants.
