Which acid is in soft drinks?
Think it through first, then pick an option.
- a Hydrochloric acid
- b Sulphuric acid
- c Carbonic acid
- d Phosphoric acid
Answer and explanation
Correct answer: c Carbonic acid
In soft drinks CO₂ and water form carbonic acid (H₂CO₃).
Why the other options are wrong
- a Hydrochloric acid: HCl is the main ingredient of toilet cleaner, not soft drinks.
- b Sulphuric acid: Sulphuric acid is used to make detergent and ammonium sulphate, not drinks.
- d Phosphoric acid: The book names only carbonic acid in soft drinks.
