What type of solution will have pH 4?
Answer and explanation
Correct answer: Acidic
The pH scale describes the acidity of an aqueous solution: pH 7 is approximately neutral, values below 7 are acidic, and values above 7 are basic. Since pH 4 is below 7, the solution has greater hydrogen-ion concentration than a neutral solution and is acidic. It is not basic or metallic, and neutrality would require a value near 7. Therefore option C is correct.
