What is the nature of a solution with pH seven?
Answer and explanation
Correct answer: Neutral
The pH scale compares hydrogen-ion concentration with the neutral reference. At approximately 25 °C, pH 7 represents a neutral solution, in which acidic and basic effects are balanced. Thus option A is correct. A pH below 7 indicates acidity and a pH above 7 indicates basicity. “Corrosive” describes a possible chemical effect, not a specific pH classification, so it is not the answer.
