The dry ice color show is a chemical demonstration for the formation of carbonic acid (H2CO3) by the dissolution of dry ice, the solid form of carbon dioxide (CO2) into water. Carbonic acid is a weak acid and solutions are not hazardous.
What is the chemical reaction for dry ice?
When dry ice is added, a significant amount of carbon dioxide dissolves in water, creating carbonic acid. H2O + CO2 - ->H2CO3 . The indicator soon responds to the presence of H+; the indicators molecular structure changes so that its electron energy levels are no longer the same, altering its response to light.
