What is the nature of a solution when its pH is less than seven?
Answer and explanation
Correct answer: Acidic
The pH scale indicates the acidic or basic nature of an aqueous solution. At approximately 25 °C, pH 7 is neutral; values below 7 indicate an increased hydrogen-ion concentration and therefore acidic character. Thus option A is correct. A basic solution has pH above 7, a neutral solution is around 7, and “metallic” is not a pH classification.
