identify the approximate color you would expect if you were to test each household item using a cabbage ph indicator. coffee, ph 5 baking soda solution, ph 9 bleach, ph 13 (strong base) toothpaste, ph 8 milk, ph 6.8 battery acid, ph 1, (strong acid)
Answer
Answer:
- Coffee, pH 5: Pink - red (since acidic solutions around pH 5 turn cabbage indicator pink - red).
- Baking soda solution, pH 9: Blue - green (basic solutions around pH 9 turn cabbage indicator blue - green).
- Bleach, pH 13 (strong base): Yellow (very strong bases around pH 13 turn cabbage indicator yellow).
- Toothpaste, pH 8: Blue (basic solutions around pH 8 turn cabbage indicator blue).
- Milk, pH 6.8: Pink (slightly acidic solutions around pH 6.8 turn cabbage indicator pink).
- Battery acid, pH 1 (strong acid): Red (strong acidic solutions around pH 1 turn cabbage indicator red).
Brief Explanations:
Cabbage pH indicator changes color based on the acidity or basicity of a solution. Acids turn it red - pink and bases turn it blue - green to yellow depending on the pH level.
