Question
Which of the following acids (listed with \( K_a \) values) and their conjugate base would form a buffer with a pH of 2.34?

- \( \text{HF, } K_a = 3.5 \times 10^{-4} \)

- \( \text{HIO}_3, K_a = 1.7 \times 10^{-1} \)

- \( \text{C}_6\text{H}_5\text{COOH, } K_a = 6.5 \times 10^{-5} \)

- \( \text{HClO, } K_a = 2.9 \times 10^{-8} \)

- \( \text{HClO}_2, K_a = 1.1 \times 10^{-2} \)
