Equilibria involving carbon dioxide in aqueous solution
In association with Nuffield Foundation

Use this demonstration or class practical to illustrate changes to equilibria in carbonated soda water. Includes kit list and safety instructions.
In this experiment, students place soda water in a syringe. As they pull the plunger out to reduce the pressure above it, they can observe bubbles of carbon dioxide forming (‘out-gassing’) as its solubility decreases.
