Two solutions X and Y have pH values 3 and 11 respectively. Which statement is correct?

Answer and explanation

Correct answer: X is more acidic and Y is more basic

The pH scale expresses hydrogen-ion concentration: values below 7 indicate acidic solutions, 7 is neutral, and values above 7 indicate basic solutions. Therefore X, with pH 3, is acidic, while Y, with pH 11, is basic. The numerical separation also shows that they do not have the same acidic character. Hence the correct statement is option B; option A reverses the meanings.
