What is the pH range of acidic solutions?

• A. 7.1 to 14
• B. 0 to 6.9
• C. 6.9 to 7.5
• D. Neutral to alkaline

Answer: (B)

The pH scale ranges from 0 to 14, with lower values indicating acidity, a midpoint at 7 representing neutrality (pure water), and higher values indicating alkalinity (basic solutions). Acidic solutions are defined as those with a pH less than 7, which corresponds to a pH range from 0 to 6.9. This range encompasses a variety of acidic substances, with strong acids having pH values close to 0, while weak acids approach the upper limit near 7. Thus, the correct answer clearly identifies the appropriate pH range for acidic solutions.
