The pKa value of acetic acid is:
Correct answer: C. 4.76
- A. 1.34
- B. 3.52
- C. 4.76
- D. 2.53
Explanation
The pK of an acid indicates its strength; lower pK means stronger acid. For acetic acid (CH₃COOH), the pKa is experimentally determined to be 4.76. a a This reflects that acetic acid is a weak acid.
