If a solution has pH 7, what will be its nature?
Answer and explanation
Correct answer: Neutral
The pH scale expresses the acidic or basic nature of an aqueous solution. At approximately 25°C, pH 7 represents neutrality, where hydrogen-ion and hydroxide-ion concentrations are equal. Values below 7 are acidic and values above 7 are basic. Therefore option C, neutral, is correct. The answer assumes the usual school-level aqueous pH scale and conditions; pH 7 is not highly acidic or basic.
