Why does hydrogen carbonate indicator turn from red to yellow in the presence of carbon dioxide?
The indicator in your hydrogen carbonate (probably Phenol red) is set to turn yellow if it falls below a certain pH level
The pH range of Phenol red are 8.4 (red) 6.8 (yellow)
the pKa of NaHCO3 is 6.3 so if the pH drop below pH 6.3 the stuff will turn yellow
CO2 will react with water to form carbonic acid lowering the pH:
CO2 + H2O --> H2CO3
so the resulting NaHCO3 will have a pH lower that 6.3 and the material will turn yellow.
