Among two acids of the same concentration, the one with lower pH will be what?
Answer and explanation
Correct answer: More acidic
The governing concept is the inverse relationship between pH and hydrogen-ion concentration. A lower pH means a larger effective concentration of hydrogen ions and therefore greater acidity. Since the two solutions already have the same stated concentration, the acid with the lower pH is more acidic, making option A correct. It is not basic or neutral, and lower pH alone does not mean that the substance must be less reactive in every reaction.
