What is the nature of a solution with pH less than 7?

Answer and explanation

Correct answer: Acidic

At about 25°C, the pH scale classifies a solution with pH 7 as neutral; values below 7 indicate an acidic solution, while values above 7 indicate a basic solution. A lower pH generally means a greater concentration of hydrogen ions and stronger acidity, though strength also depends on concentration. Thus the correct classification is acidic, option A; basic and neutral describe the other pH ranges, and metallic is not a pH classification.
