Question
The nature of carbon dioxide is
- Acidic
- Basic
- Amphoteric
- Slightly acidic
Hint:
Carbon dioxide is slightly acidic.
The correct answer is: Slightly acidic
Carbon dioxide (CO2) in the atmosphere makes all rain slightly acidic because carbon dioxide and water combine to form carbonic acid, commonly known as carbonated water.
Carbon dioxide excess can increase acidity in the blood.
