### Question:What is the pH of a buffer containing 0.55 M HF (aq) and 0.55 M NaF (aq)?### Possible Answers:- ○ 1.70- ○ 3.15- ○ 0.26- ○ 8.44- ○ 10.85### Explanation:This question tests your understanding of buffer solutions and their pH calculations. A buffer is a solution containing a weak acid and its conjugate base, which resists changes in pH when small amounts of acid or base are added. For this problem, use the Henderson-Hasselbalch equation:\[ \text{pH} = \text{pKa} + \log\left(\frac{\text{[A}^-]}{\text{[HA]}}\right) \]Where:- \(\text{pKa}\) of HF is approximately 3.17- [A\(^-\)] is the concentration of the conjugate base, F\(^-\) from NaF- [HA] is the concentration of the weak acid, HFSince both concentrations are equal, the pH equals the \(\text{pKa}\).
