Salicylic acid, HOC6H4CO2H, and its derivatives have been used as pain relievers for a long time. Salicylic acid occurs in small amounts in the leaves, bark, and roots of some vegetation (most notably historically in the bark of the willow tree). Extracts of these plants have been used as medications for centuries. The acid was first isolated in the laboratory in 1838. Both functional groups of salicylic acid ionize in water, with Ka = 1.0x10 for the CO2H group and 4.2x10 13 for the OH group. What is the pH of a saturated solution of the acid (solubility = 1.8 g/L). (Please use standard notation and don't enter units for your answer.)
