To classify different substances as acidic, basic, or neutral, we can look at their pH levels.
- Distilled Water: Neutral. Distilled water has a pH level of around 7, which means it is neither acidic nor basic.
- Tap Water: Neutral to slightly basic. The pH of tap water can vary based on location but typically hovers around 7 to 8.
- Black Coffee: Acidic. Black coffee generally has a pH ranging from 4.5 to 6, making it acidic.
- Lemon Juice: Acidic. Lemon juice contains citric acid and usually has a pH between 2 and 3, indicating it is highly acidic.
- Household Bleach: Basic. Household bleach is strongly basic with a pH of around 12 to 13.
- Egg White Albumin: Slightly basic. The pH of egg whites ranges from about 7.6 to 8.0, classifying it as slightly basic.
Understanding the pH of these common substances can help us in various everyday applications, from cooking to cleaning.
