Problem

Given the following pKa values, which is the strongest acid of those listed in the answers?

HClO2 (pKa = 2.00)

CCl3COOH (pKa = 0.52)

HIO3 (pKa = 0.77)

HBrO2 (pKa = 4.69)

HN3  (pKa = 4.72)

Solution

Use the pKa values to determine the strongest acid among the listed compounds


Recall that pKa is:


pKa = -log Ka
