A solution with a pH of 3.0 would be classified as which?

A solution with a pH of 3.0 would be classified as which?

• A. Base
• B. Neutral
• C. Acid
• D. Salt

Answer: (C)

pH is a measure of how acidic or basic a solution is, with 7 being neutral. Values below 7 indicate acidity, and the lower the number, the stronger the acid. A pH of 3.0 sits well below 7, which means the solution has a relatively high concentration of hydrogen ions and behaves as an acid. Bases have pH above 7, and neutral is exactly 7, while a salt’s pH depends on its specific ions and isn’t defined as acidic just from a pH value like 3.0. For context, common acids such as lemon juice or vinegar sit in the acidic range around pH 2–3, illustrating why this solution is classified as an acid.
