The correct statement is:
**The substance with the lower pH has 1,000 times as many hydrogen ions per volume of water.**
This is because the pH scale is logarithmic, meaning each whole number change on the scale (like going from pH 3 to pH 6) represents a tenfold change in hydrogen ion concentration. Therefore, a pH of 3.0 has 1,000 times more hydrogen ions than a pH of 6.0.
