The Reaction Between Sodium Bicarbonate and Citric Acid
Observing the Reaction
When sodium bicarbonate and citric acid are combined, an effervescent reaction occurs. This reaction is commonly observed when baking soda is mixed with acid in recipes or cleaning solutions.
Upon mixing, you may notice a vigorous release of gas bubbles and the formation of a frothy solution. This effervescence is a result of carbon dioxide gas being produced as a product of the reaction.
The reaction between sodium bicarbonate and citric acid is not only fascinating but also has practical applications in various fields. For instance, in the culinary world, this reaction is essential for making fluffy cakes and bread. The release of carbon dioxide gas causes the dough or batter to rise, resulting in a light and airy texture.
Furthermore, this reaction is also utilized in the cleaning industry. The effervescent reaction between sodium bicarbonate and citric acid helps to break down stubborn stains and dirt. The carbon dioxide gas produced acts as a gentle abrasive, aiding in the removal of grime.
Chemical Changes Involved
The reaction between sodium bicarbonate and citric acid involves a double displacement reaction. The citric acid donates a proton (H+) to the bicarbonate ion (HCO3–), forming carbonic acid (H2CO3).
Carbonic acid then rapidly decomposes into water (H2O) and carbon dioxide (CO2). This release of carbon dioxide gas causes the effervescence observed during the reaction.
It is interesting to note that carbonic acid is a weak acid, meaning it does not fully dissociate into its ions. This partially dissociated state allows for the reversible reaction between carbonic acid and water. In the presence of excess carbon dioxide, carbonic acid can re-form, leading to a dynamic equilibrium.
The production of carbon dioxide gas in this reaction is not only responsible for the effervescence but also has implications in other areas. Carbon dioxide is a greenhouse gas that contributes to climate change. Understanding the chemistry behind its production is crucial for developing strategies to mitigate its impact.

To balance the equation for the reaction between sodium bicarbonate and citric acid, we must ensure that the number of atoms of each element is the same on both sides.
The balanced equation for the reaction is as follows:
- 3NaHCO3 + C6H8O7 → 3CO2 + 3H2O + Na3C6H5O7
By balancing the equation, we ensure that three molecules of sodium bicarbonate react with one molecule of citric acid, producing three molecules of carbon dioxide, three molecules of water, and one molecule of sodium citrate.
The Role of Coefficients in Balancing
Coefficients are used in chemical equations to adjust the number of molecules involved in a reaction. They provide a way to balance the equation by changing the quantity of each substance.
In the case of the sodium bicarbonate and citric acid reaction, the coefficient 3 is applied to sodium bicarbonate and carbon dioxide to achieve the balanced equation.
Now, let’s delve deeper into the process of balancing chemical equations. Balancing an equation involves adjusting the coefficients in front of each compound or element to ensure that the number of atoms on both sides of the equation is equal. This is necessary because chemical reactions must obey the law of conservation of mass, which states that matter cannot be created or destroyed.
When balancing an equation, it is important to start with the most complex compounds or polyatomic ions and work your way down to the simpler elements. In the given equation, we have sodium bicarbonate (NaHCO3) and citric acid (C6H8O7). These compounds contain multiple atoms of different elements, which need to be balanced.
By examining the equation, we can see that there are three sodium bicarbonate molecules on the left side, but only one sodium citrate molecule on the right side. To balance the sodium atoms, we need to multiply the sodium citrate coefficient by 3, resulting in 3Na3C6H5O7. Now, both sides have the same number of sodium atoms.
Next, let’s focus on the carbon atoms. There are six carbon atoms in the citric acid molecule on the left side, but only one carbon dioxide molecule on the right side. To balance the carbon atoms, we need to multiply the carbon dioxide coefficient by 6, giving us 3CO2. Now, both sides have an equal number of carbon atoms.
Finally, let’s consider the hydrogen and oxygen atoms. On the left side, there are 8 hydrogen atoms in the citric acid molecule and 3 hydrogen atoms in each sodium bicarbonate molecule, resulting in a total of 11 hydrogen atoms. To balance the hydrogen atoms, we need to multiply the water coefficient by 3, resulting in 3H2O. Now, both sides have an equal number of hydrogen atoms.
Regarding the oxygen atoms, there are 14 oxygen atoms in the citric acid molecule on the left side, but only 6 oxygen atoms in the carbon dioxide and water molecules on the right side. To balance the oxygen atoms, we need to multiply the sodium citrate coefficient by 7, resulting in 7Na3C6H5O7. Now, both sides have an equal number of oxygen atoms.
Through this step-by-step process, we have successfully balanced the equation for the reaction between sodium bicarbonate and citric acid. It is important to note that the coefficients represent the relative quantities of each substance involved in the reaction and should always be in the simplest whole number ratio.
