Final answer:
The pH scale categorizes solutions based on acidity or basicity. A pH of 5 indicates an acidic solution.
Explanation:
The pH scale is a measure of a solution's acidity or basicity, ranging from 0 to 14. A solution with a pH of 5 would be classified as acidic since it is below 7 on the pH scale. Solutions below pH 7 are considered acidic, those at pH 7 are neutral, and those above pH 7 are basic (alkaline).
