A small amount of base is added to an acidic solution and pH changes from 2 to 3. What is the correct conclusion?

Answer and explanation

Correct answer: Acidity decreased, but the solution is still acidic

The pH scale describes hydrogen-ion concentration, and a neutral solution has pH 7 at ordinary school-level treatment. A rise from pH 2 to pH 3 means the hydrogen-ion concentration has decreased by a factor of ten, so the solution has become less acidic. However, pH 3 is still below 7, meaning it remains acidic. Thus A is correct; B would require pH above 7, C reverses the ion change, and D ignores the measured change.
