A solution has pH 11. What will be its nature?
Answer and explanation
Correct answer: Basic
The pH scale classifies aqueous solutions: pH 7 is neutral, a pH below 7 indicates acidity, and a pH above 7 indicates basicity. Because the given pH is 11, it is clearly greater than 7, so the solution is basic and has a comparatively greater hydroxide-ion concentration. It cannot be acidic or neutral, while metallic describes a material rather than its pH nature.
