Question

Soda is carbonated because is has carbon dioxide gas dissolved in it. Which of these treatments will help keep the soda carbonated for a longer period of time?
A) Shake the soda.
B) Keep the soda warm.
C) Keep the soda cold.
D) Open the soda bottle.

Answer 1

Keep the soda cold. Most gases are more soluble at lower temperatures and less soluble at higher temperatures. In order to keep the soda carbonated for the longest time possible, we want the \[CO _{2}\] to remain dissolved. At higher temperatures, the \[CO _{2}\] will escape the mixture faster and the soda goes flat.
