Chemical Reactions
Introduction
In this paper you learn about the reactions that occur between backing soda and lemon juice. We will also describe what is occurring with the molecules on a molecular level. Lastly we will explain what chemical bonds are formed and or broken when lemon juice and backing soda.
Observations of the Reactants When most people hear baking soda they think of the bright orange box sitting in their pantry or refrigerator soaking up the foul odors that have come about from the onions or fish. Some may think of pancakes or baking a cake. Baking powder is a fine white substance with the consistency of powdered sugar. Baking soda is a chemical base. Another substance most people do not recognize as a chemical in their household is Lemon Juice. This is a liquid mixture of water and citric acid. Its color is mildly foggy and a pale yellow. Lemon juice is a chemical acid and when mixed with a base like baking soda creates 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 due to its large increase in entropy associated with the gas formation. In this reaction, you will notice the solution bubbling and foaming due to the CO2 production.
The reaction of lemon juice and baking soda is as follows:
C6H8O7 + 3NaHCO3 <---> Na3C6H5O7 + 3H2CO
Essentially, one molecule of citric acid will react with three molecules of sodium bicarbonate. This will form one molecule of sodium citrate and three molecules of carbonic acid. It is a very exothermic chemical reaction.
