Which Gas is used in the preparation of Soft drinks? Answer: Carbon dioxide

The gas used to prepare soft drinks is carbon dioxide (CO₂) in the process of carbonation. This colorless, odorless gas is dissolved under pressure into water, which creates the characteristic "fizz" or sparkle. Beyond providing the effervescence, carbon dioxide also contributes a tangy taste, prevents spoilage by acting as a preservative, and helps maintain the beverage's shelf life.
