What pH range indicates an acidic solution?

• A. 0 to 3
• B. 3 to 6
• C. 6 to 7
• D. 7 to 14

Answer: (B)

An acidic solution is characterized by a pH value that is less than 7. pH values range from 0 to 14, where 0-6 indicates acidity, 7 is neutral, and 8-14 indicates alkalinity (basicity). The range of 3 to 6 specifically includes moderately acidic to less acidic solutions. A pH value of 3 is considered strongly acidic, while a pH of 6 is just below neutral, indicating a weakly acidic solution. Both values within this range confirm that the solution exhibits acidic properties. In contrast, a pH range of 0 to 3 represents strong acids, while a range of 6 to 7 indicates neutrality. Any value above 7 indicates an alkaline solution, which does not meet the criteria for acidity. Hence, the correct range indicating an acidic solution is from 3 to 6.
