Dry Ice Sublimation | CO₂ & Universal Indicator Chemistry Experiment

A chemistry demonstration showing the sublimation of dry ice (solid carbon dioxide) and its effect on a solution containing universal indicator.

As carbon dioxide dissolves in water, the pH changes and the universal indicator changes colour.

This experiment demonstrates:
• Sublimation of dry ice
• Carbon dioxide dissolving in water
• Changes in pH
• Universal indicator colour changes
