A solution with pH less than which value is considered acidic?

Answer and explanation

Correct answer: Seven

The governing concept is the pH scale, which indicates the hydrogen-ion concentration of an aqueous solution. At ordinary school-level conditions, pH 7 is neutral; values below 7 indicate acidic solutions, while values above 7 indicate basic solutions. Therefore option A, seven, is correct. Ten and fourteen are alkaline-side values, and zero is an acidic pH value rather than the boundary asked for.
