If the pH value is greater than 7, how is the solution considered?
Answer and explanation
Correct answer: Basic
The pH scale describes the acidic or basic nature of an aqueous solution. A pH of 7 is generally neutral, values below 7 indicate acidity, and values above 7 indicate basicity or alkalinity. Since the question gives a pH greater than 7, the solution is basic. Option A describes pH below 7, option C describes pH 7, and insolubility is unrelated to pH. Therefore, option B is correct.
