What is the nature of a solution with pH equal to 7?
Answer and explanation
Correct answer: Neutral
The pH scale compares acidity and basicity through hydrogen-ion concentration. Under standard school conditions, pH 7 represents a neutral solution: it is neither acidic nor basic in the intended classification. Pure water is the usual example, although temperature and dissolved substances can affect its exact pH. Acidic solutions have pH below 7, and basic solutions have pH above 7, so option A is correct.
