Between pH six and pH three which solution will be more acidic?
Answer and explanation
Correct answer: The one with pH 3
Acidity increases as pH decreases because a lower pH represents a greater hydrogen-ion concentration. Comparing the two values, pH 3 is lower than pH 6; therefore the pH 3 solution is more acidic. Option A is correct. The solutions are not equally acidic, and both are acidic rather than neither being acidic.
