What will be the nature of a solution with pH four?

Answer and explanation

Correct answer: Acidic

The pH scale classifies aqueous solutions relative to pH 7: values below 7 are acidic, about 7 are neutral, and values above 7 are basic. Since 4 is less than 7, the solution is acidic, so option A is correct. It cannot be neutral or basic, and “metallic” is not a pH classification for a solution’s acid–base nature.
