Web8 May 2024 · The lower the pKa value of a substance, the more acidic it is in nature. 'Ka' is called acid dissociation constant whereas 'pKa' is called a -log of 'Ka'. The pKa values for the acids given in the series are as follows: - 25 - 43 - 50 - 15.5; From the above pKa value, as the compound has lower pKa value it is considered as strongest acid. As ...
