What change in nature is shown when the pH of a solution changes from seven to eleven?

Answer and explanation

Correct answer: Neutral to basic

On the pH scale, a value of 7 represents a neutral solution at ordinary school-level conditions. Values greater than 7 indicate a basic or alkaline solution, and pH 11 is therefore basic. The change from 7 to 11 shows that the solution has changed from neutral to basic. It does not become acidic, because acidic solutions have pH values below 7.
