A student is doing a project growing plants in 3 different atmospheres 1. ordinary air (but in a terrarium type environment) 2. carbon dioxide enriched (in a terrarium type environment) It is entended to use bicarbonate and citric acid to generate the carbon dioxide. 3. carbon dioxide depleted (in a terrarium type environment) Soda Lime is intended to be used to cause this. Question how can she easily show the three atmospheres have different amounts of carbon dioxide. I know bromothymol blue will show the enriched environment, but it will no show a difference between ordinary air and the depleted atmosphere. Any suggestions would be gratefully received.
