What is the pH range of acidic solutions?

• A. pH greater than 7
• B. pH equal to 7
• C. pH less than 7
• D. pH less than 14

Answer: (C)

Acidic solutions are defined by their pH values, which measure the concentration of hydrogen ions in a solution. A pH value less than 7 indicates a higher concentration of hydrogen ions, which is characteristic of acids. The pH scale ranges from 0 to 14, with 0 being highly acidic, 7 being neutral (pure water), and 14 being highly basic. Therefore, when a solution has a pH less than 7, it is classified as acidic due to the presence of excess hydrogen ions, making option C the accurate choice. This understanding is crucial for various applications in science, including chemistry, biology, and environmental science.
