If the pH value is less than 7, how is the solution considered?
Answer and explanation
Correct answer: Acidic
At about room temperature, the pH scale classifies a solution with pH 7 as neutral, a value below 7 as acidic, and a value above 7 as basic. A pH below 7 indicates a comparatively higher hydrogen-ion concentration than a neutral solution. Therefore A is correct. The value does not indicate that the solution is metallic, and it cannot be called neutral or basic under this classification.
