Question

The pH of a solution is 3. What is the concentration of \( \text{H}^+ \) ions in the solution?

• A. \( 1 \times 10^{-3} \, \text{mol/L} \)
• B. \( 3 \times 10^{-3} \, \text{mol/L} \)
• C. \( 1 \times 10^{-6} \, \text{mol/L} \)
• D. \( 3 \times 10^{-6} \, \text{mol/L} \)

Hint:

Remember: pH is the negative logarithm of the hydrogen ion concentration. A lower pH means a higher concentration of \( \text{H}^+ \) ions.
