Strong acids are those compounds which can dissociate completely into ions in solution. They can dissolve many compounds due to their high corrosive nature. Strong acids have high Ka (acid dissociation constant) values and low pKa values. The pKa of an acid is calculated as follows: pKa=-logKaKa of formic acid = 1.8×10-4 pKa of formic acid=-log1.8×10-4=3.74 Ka of propanoic acid = 1.4×10-5 pKa of propanoic acid=-log1.4×10-5=4.85 pKa of hydrofluoric acid = 3.45 pKa of oxalic acid = 1.23 The pKa value of oxalic acid is the lowest. Thus, oxalic acid is the strongest acid among the given acids. Answer: Oxalic acid (COOH)2 is the strongest acid.
