The correct statement is:
The substance with the lower pH has 1,000 times as many hydrogen ions per volume of water.
In terms of pH, each whole number change represents a tenfold change in hydrogen ion concentration. Therefore, a solution with a pH of 3.0 has 1,000 times more hydrogen ions than a solution with a pH of 6.0 (which is three pH units higher).
