If the pH value is greater than 7, what is the nature of the solution?

Answer and explanation

Correct answer: Basic

The pH scale describes the acidic or basic nature of an aqueous solution. A pH of 7 is conventionally neutral at about room temperature, while values greater than 7 indicate a lower hydrogen-ion concentration and a higher relative hydroxide-ion concentration. Therefore, the solution is basic, so option B is correct. Acidic means pH below 7, neutral means pH 7, and “salt-free” is not a pH classification.
