Consider two solutions: solution X has a pH of 4; solution Y has a pH of 7. From this information, we can reasonably conclude that ________.
A) solution Y has no free hydrogen ions (H+)
B) the concentration of hydrogen ions in solution Y is 1000 times as great as the concentration of hydrogen ions in solution X
C) the concentration of hydrogen ions in solution X is 3 times as great as the concentration of hydrogen ions in solution Y
D) the concentration of hydrogen ions in solution X is 1000 times as great as the concentration of hydrogen ions in solution Y

The pH scale is logarithmic, meaning each whole pH value below 7 is ten times more acidic than the next higher value. Therefore, a solution with a pH of 4 has 10^3 (or 1000) times more hydrogen ions than a solution with a pH of 7.
