WebThe pKa of ethanol is about 17, while the pKa of acetic acid is about 5: this is a 10 12 -fold difference in the two acidity constants. In both compounds, the acidic proton is bonded to an oxygen atom. How can they be so different in terms of acidity? We begin by considering the conjugate bases. WebTherefore, pKa was introduced as an index to express the acidity of weak acids, where pKa is defined as follows. For example, the Ka constant for acetic acid (CH 3 COOH) is 0.0000158 (= 10-4.8), but the pKa constant is 4.8, which is a simpler expression. In addition, the smaller the pKa value, the stronger the acid.
