Question

1. Listed below are two organic acids and their pKa values. Calculate the acid dissociation constant, Ka, for each and indicate which of the two is the stronger acid.

HC₇H₅O₂ pKa = 4.20

HC₅H₉O₂ pKa = 5.03

To calculate the acid dissociation constant (Ka) from the pKa value, use the formula:

\[ \text{Ka} = 10^{-\text{pKa}} \]

The lower the pKa value, the stronger the acid, as it indicates a higher degree of ionization.
