What is the chemical equation for the fizzing reaction of soda water?

• A. H2CO3 -> H2O + CO2
• B. H2O + O2 -> H2O2
• C. CO2 + H2O -> H2CO3
• D. H2 + CO2 -> H2CO3

Answer: (A)

The fizzing reaction of soda water involves the dissociation of carbonic acid into water and carbon dioxide gas. When soda water is opened, the pressure is released, leading to the escape of dissolved carbon dioxide. This process occurs as the carbonic acid (H2CO3) breaks down into water (H2O) and carbon dioxide (CO2), which is responsible for the bubbles or fizzing that you observe. The representation of this chemical change highlights the conversion of a compound into its constituents, illustrating the dynamic nature of chemical compounds under different pressure conditions. This reaction is a common example of how carbon dioxide is involved in the carbonic acid equilibrium in carbonated beverages, making it the correct choice.
