If the pH value increases from 7 to 11, what will be the nature of the solution?

Answer and explanation

Correct answer: Basic

A pH of 7 indicates a neutral solution at ordinary school-level conditions. When pH rises above 7, the solution is classified as basic or alkaline because its hydrogen-ion concentration is lower relative to hydroxide-ion concentration. Since pH 11 is well above 7, option B is correct. Options A and C describe acidity, while option D incorrectly treats all pH values as neutral.
