question 63

Multiple Choice

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 X is 30 times as great as the concentration of hydrogen ions in solution Y.
• C)the concentration of hydrogen ions in solution Y is 1,000 times as great as the concentration of hydrogen ions in solution X.
• D)the concentration of hydrogen ions in solution X is 3 times as great as the concentration of hydrogen ions in solution Y.
• E)None of the other answer choices correctly describes these solutions.
