CO2 in a new and old way. Baking soda is sodium bicarbonate (NaHCO3). When it is mixed with an acid liquid it releases the gas carbon dioxide (CO2).

(CO2):
NaHCO3 + H+ ----- Na+ + H20 + CO2
(soda) (acid) (sodium) (water) (gas)

acid: vinegar would evaporate to aquarium with CO2 so I think that citric
acid would be better.
Drops of dissolved in a water soda dropped to disolved in a water citric
acid will make a clear CO2.
Is there any Chemist who could calculate it?
