What is the pH range associated with acids?

• A. 0-6.9
• B. 7-7.9
• C. 8-14
• D. 0-14

Answer: (A)

The pH range associated with acids is accurately represented as 0-6.9. In the pH scale, values below 7 indicate acidity, with lower values corresponding to stronger acids. This scale measures the concentration of hydrogen ions in a solution, and as the concentration increases, the pH value decreases. A pH of 7 is considered neutral, which is typically that of pure water. Values from 8 to 14 denote alkalinity, indicating a base rather than an acid. Therefore, the range of 0-6.9 effectively captures the spectrum of acidic solutions, confirming that option A reflects the correct pH association for acids.
