If a solution has pH 2, what will be its nature?
Answer and explanation
Correct answer: Strongly acidic
The pH scale indicates the concentration of hydrogen ions: values below 7 represent acidic solutions, 7 is neutral, and values above 7 are basic. A pH of 2 is far below 7 and indicates a high hydrogen-ion concentration, so the solution is strongly acidic. Therefore, option A is correct. It cannot be neutral or basic, and calling it weakly basic reverses the meaning of the pH scale.
