Here’s the classification of each example as either an acid or a base:
- Cleaning products - Base
- A boy puckering his lips - Not an acid or base (this is a physiological reaction, not a substance)
- Antacid tablet - Base
- Carbonic acid - Acid
- Pickles - Acid (due to vinegar or brine used in pickling)
- Bleach - Base
- Soap - Base
- Oranges - Acid (due to citric acid)
To summarize:
- Acid: Carbonic acid, Pickles, Oranges
- Base: Cleaning products, Antacid tablet, Bleach, Soap
The "A boy puckering his lips" does not fall under either category as it's not a chemical substance.
