Therefore, pKa was introduced as an index to express the acidity of weak acids, where pKa is defined as follows. ... In addition, the smaller the pKa value, the stronger the acid. For example, the pKa value of lactic acid is about 3.8, so that means lactic acid is a stronger acid than acetic acid.

The Ka value is less than one because acetic acid is a weak acid. To find the pKa of acetic acid we take the negative log of the Ka value. So the negative log of 1.8 times 10 to the negative fifth is equal to 4.74. origins of the silk road
