A pH example refers to a specific substance and its corresponding pH value. The pH scale measures the acidity or alkalinity of a solution. A pH value of 7 is neutral, while values below 7 are acidic and values above 7 are basic.
Here are some common pH examples:
-
Acidic:
- Vinegar: pH 2.4
- Lemon juice: pH 2.0
- Stomach acid: pH 1.5
- Orange juice: pH 3.5
-
Neutral:
- Pure water: pH 7
-
Basic:
- Baking soda: pH 9
- Limewater: pH 12
- Ammonia: pH 11.5
- Seawater: pH 8.1
Understanding these pH examples helps visualize the scale and its relevance in everyday life.
