    a reaction. Reactions that occur Mixing lemon juice with baking soda gives you a chemical reaction.  The lemon juice contains citric acid.  The citric acid from the lemon juice will donate a hydrogen ion (H+) to the bicarbonate or baking soda (NaHCO3).  When the bicarbonate is mixed into solution‚ the bicarbonate acts as a base and takes the H+ ion from the citric acid to form carbonic acid (H2CO3) and carbon dioxide (CO2).  Whenever a chemical reaction produces gas‚ it will be highly favored
