Between two basic solutions of pH 10 and pH 13, which one is more basic?

Answer and explanation

Correct answer: The one with pH 13

On the pH scale, values above 7 indicate basic solutions, and a higher pH generally means a lower hydrogen-ion concentration and greater basicity. Since 13 is greater than 10, the pH 13 solution is more basic. The three-unit difference also corresponds to a thousand-fold difference in hydrogen-ion concentration under comparable conditions. Options C and D incorrectly call the solutions acidic or neutral, so option B is correct.
