If a solution has a pH of 6, compared to a solution with a pH of 3, would it contain more or fewer hydrogen ions (H+)?

It would contain fewer hydrogen ions.
Explanation: pH is a measure of the concentration of hydrogen ions in a solution, on a logarithmic scale. The lower the pH, the higher the concentration of hydrogen ions, so a pH of 3 has a higher concentration of hydrogen ions than a pH of 6.
