What is the general nature of a solution when its pH is less than 7?

Answer and explanation

Correct answer: Acidic

The governing concept is the pH scale. At approximately 25°C, a solution with pH 7 is considered neutral, values below 7 indicate increasing hydrogen-ion concentration and acidic nature, and values above 7 indicate basic nature. Thus a pH less than 7 identifies an acidic solution, making option A correct. Basic and neutral describe the other pH ranges, while insolubility concerns dissolving and is unrelated to pH.
