Fizzy drinks contain dissolved CO2. The CO2 reacts with H2O to form weak acid which is called:
Correct answer: B. Carbonic acid
- A. Acetic acid
- B. Carbonic acid
- C. Lactic acid
- D. Formic acid
Explanation
The weak acid formed when CO2 reacts with water in fizzy drinks is called "Carbonic acid." Therefore, the correct option is "Carbonic acid" as it is the specific weak acid formed when CO2 dissolves in water.

About Bronsted-Lowry and Lewis Concepts
The Brønsted-Lowry concept defines acids as proton donors and bases as proton acceptors, producing conjugate acid-base pairs. The Lewis concept extends the idea to electron-pair acceptors and donors, so compounds such as BF3 and NH3 can be treated as acid and base even without proton transfer, unlike the Arrhenius definition.
