While the exact chemical formula for Sprite is a trade secret, we can break down its main ingredients and their chemical compounds:

* Carbonated Water: H₂O + CO₂

* Sugar: C₁₂H₂₂O₁₁ (Sucrose)

* Citric Acid: C₆H₈O₇

* Natural Flavors: This is where the proprietary blend comes in. These flavors are typically derived from citrus fruits (lemon and lime) and may include other compounds for specific taste and aroma.

* Sodium Citrate: Na₃C₆H₅O₇ (Used for acidity regulation and flavor enhancement)

* Other ingredients: Sprite may contain additional minor ingredients like caffeine, preservatives, and coloring agents.

Important Note: The specific proportions of these ingredients are not publicly available, making the exact chemical formula of Sprite a trade secret.
