A very strong acid would have a pH closer to which value?

• A. 7
• B. 14
• C. 1
• D. 0

Answer: (C)

A very strong acid would have a pH closer to 0. The pH scale ranges from 0 to 14, with lower values indicating higher acidity. A strong acid dissociates completely in water, releasing a high concentration of hydrogen ions (H⁺). As the concentration of hydrogen ions increases, the pH decreases. A pH of 0 indicates a very high concentration of hydrogen ions which is characteristic of strong acids. For example, a hydrochloric acid solution at a concentration of 1 M has a pH of 0. Conversely, a pH of 7 is neutral (pure water), and a pH of 14 indicates a very strong base, where hydroxide ions (OH⁻) predominate. Thus, a pH closer to 0 is expected for very strong acids, reflecting their significant strength and ability to donate protons in solution.
