Between pH eight and pH eleven, which solution will be more basic?
Answer and explanation
Correct answer: The one with pH eleven
The governing concept is the pH scale. For aqueous solutions, a higher pH indicates a lower hydrogen-ion concentration and greater basicity. Since 11 is higher than 8, the solution with pH 11 is more basic, so option A is correct. The solutions are not equally basic, and neither can be rejected merely because both values lie on the basic side of the scale.
