We're being asked to identify the strongest acid based on the given pK values.
Ka represents the acid dissociation constant and it measures the strength of weak acids. In general:
• The higher the Ka the stronger the acid and the greater the concentration of H+
Ka is the negative base-10 logarithm of the base dissociation constant (Ka) of a solution.
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)
