Answer:
c. 7.14
Explanation:
The buffer solution is formed by a weak acid ( hypochlorous acid, HClO) and its conjugate base (hypochlorite ClO⁻, coming from sodium hypochlorite NaClO). We can calculate the pH using the Henderson-Hasselbach equation.
pH = pKa + log [base]/[acid]
pH = -log 3.8 × 10⁻⁸ + log 0.111/0.211
pH = 7.14
