Which gas is found in soda water?

Correct option is C

The correct answer is option (c): Carbon dioxide
Explanation:
Soda water, also known as carbonated water, is water into which carbon dioxide (CO₂) gas has been dissolved under pressure.
It creates a refreshing, fizzy sensation due to the release of carbon dioxide bubbles when the pressure is released (e.g., when you open a bottle of soda water).
Role of Carbon Dioxide in Soda Water:
Carbon dioxide dissolves in water under high pressure, forming carbonic acid (H₂CO₃), which gives soda water its slightly tangy taste.
When the bottle is opened, the pressure is released, and the carbon dioxide escapes in the form of bubbles.
 

 Uses of other gases:

•  Hydrogen:
  Fuel: Used in rockets and hydrogen fuel cells.
  Chemical Industry: For ammonia and hydrogenation.
  Energy: Storage for renewable energy systems.
  
• Nitrogen:
  Industrial: In fertilizers and as an inert gas.
  Food: Preserves freshness in food packaging.
  Medical: Liquid nitrogen for cryotherapy.
  
•  Freon:
  Refrigeration: Used as a refrigerant in ACs and fridges.
  Industrial: In aerosol propellants (though phased out due to environmental concerns).
