Science Behind the Project:
Lemon juice contains citric acid which when mixed with baking soda (sodium bicarbonate) reacts to form carbon dioxide and sodium citrate, which causes the liquid to fizz and bubble. Citric acid is a common food additive used in soft drinks as a preservative and flavoring.
Did you know that citric acid is also found in drink mixes like Kool Aid? You can watch this chemical reaction by mixing powdered Kool-Aid and baking soda in a cup, and adding water.
