Solution
Solution Steps
Step 1: Understanding pH
The pH scale measures how acidic or basic a substance is. It ranges from 0 to 14. A pH of 7 is considered neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic (alkaline).
Step 2: Matching pH values to descriptions
pH 7: This is exactly in the middle of the pH scale, so it represents a neutral substance.
pH 3: This is less than 7, meaning it corresponds to an acidic substance.
pH 11: This is greater than 7, indicating a basic (alkaline) substance.
