  1. The Secrets of Carbonation Bob Koresh and Tyler Pedracine

  2. The State of a Closed Bottle of Carbonated Water • Carbonated beverages are solutions with carbon dioxide gases dissolved into them. • When the bottle is closed the pressure of the gas above the solution is very high • a lot of carbon dioxide can be dissolved • Henry’s Law

  3. Opening a Carbonated Beverage • When a carbonated beverage is opened it becomes supersaturated. • Opening the bottled beverage allows the pressure above the solution to decrease. • With less pressure, less carbon dioxide can be dissolved • The excess carbon dioxide begins to fizz out. • When fizzing stops the solution is saturated again.

  4. Temperature and Carbonation • In general, as heat increases, solubility of gases decreases. • When a liquid reaches its boiling point, no gas can be dissolved. • Which means a hot bottle of carbonated water will go flat quicker than a cooler bottle of carbonated water

  5. How to Make Your Beverage Unsaturated • To make your carbonated beverage unsaturated you can lower the temperature while keeping pressure constant

  6. Assuming you like fizzy soda, what temperature (hot or not hot) would you drink a soda ? WHY?

  7. When the bottle is opened, before any thing happens,how would the solution be described? • Saturated • Concentrated • Supersaturated • Superconcentrated • Unsaturated

  8. Assuming you like fizzy soda, what temperature (hot or not hot) would you drink a soda ? WHY? • You would drink the soda when it is not hot, because the warmer the soda the less carbon dioxide can be dissolved (i.e., the solubility of carbon dioxide in water goes down as water gets hotter).

  9. When the bottle is opened, before any thing happens,how would the solution be described? • B. Supersaturated
