# A student measures the \(\text{pH}\) of an aqueous solution to be \(3.40\) at \(25\ ^\circ\text{C}\). What is the concentration of \(\text{H}^+\text{(aq)}\) in the solution?

A student measures the \(\text{pH}\) of an aqueous solution to be \(3.40\) at \(25\ ^\circ\text{C}\). What is the concentration of \(\text{H}^+\text{(aq)}\) in the solution?

- **A.** \(4.0 \times 10^{-4}\text{ M}\)
- **B.** \(2.5 \times 10^{-3}\text{ M}\)
- **C.** \(3.4 \times 10^{-3}\text{ M}\)
- **D.** \(4.0 \times 10^{-3}\text{ M}\)
