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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0a32ed39-825c-4317-b134-edd3dba92050%2F643f14d0-47b7-4d00-9319-f960cb7a13a8%2F25hgyjr_processed.png&w=3840&q=75)
