Introduction
Citric acid, a naturally occurring compound found in citrus fruits, is widely used in various industries, including food, pharmaceuticals, and cosmetics. In this article, we will explore the reaction between citric acid and baking soda, a common household ingredient. The reaction between citric acid and baking soda is a classic example of a chemical reaction that produces carbon dioxide gas, water, and sodium citrate.
The Chemical Equation
The chemical equation for the reaction between citric acid and baking soda is:
In this equation, citric acid (H3C6H5O7) reacts with sodium bicarbonate (NaHCO3) to produce carbon dioxide (CO2), water (H2O), and sodium citrate (Na3C6H5O7).
Understanding the Reaction
The reaction between citric acid and baking soda is a neutralization reaction, where the acid (citric acid) reacts with the base (sodium bicarbonate) to produce a salt (sodium citrate) and water. The reaction is exothermic, meaning that it releases heat energy.
Calculating the Number of Moles of Citric Acid
To calculate the number of moles of citric acid, we need to know the molar mass of citric acid. The molar mass of citric acid is 192.12 g/mol.
Given that the sample of citric acid is 13.00 g, we can calculate the number of moles of citric acid as follows:
Number of moles of citric acid = mass of citric acid / molar mass of citric acid = 13.00 g / 192.12 g/mol = 0.0677 mol
Calculating the Number of Moles of Baking Soda
The chemical equation shows that 3 moles of baking soda react with 1 mole of citric acid. Therefore, the number of moles of baking soda required to react with 0.0677 mol of citric acid is:
Number of moles of baking soda = 3 x number of moles of citric acid = 3 x 0.0677 mol = 0.2031 mol
Calculating the Mass of Baking Soda
The molar mass of baking soda is 84.01 g/mol. Therefore, the mass of baking soda required to react with 0.2031 mol of citric acid is:
Mass of baking soda = number of moles of baking soda x molar mass of baking soda = 0.2031 mol x 84.01 g/mol = 17.15 g
Conclusion
In conclusion, the reaction between citric acid and baking soda is a classic example of a chemical reaction that produces carbon dioxide gas, water, and sodium citrate. By calculating the number of moles of citric acid and baking soda required to react, we can determine the mass of baking soda required to react with a given sample of citric acid.

A 13.00 g Sample of Citric Acid: Understanding the Reaction with Baking Soda - Q&A ===========================================================
Introduction
In our previous article, we explored the reaction between citric acid and baking soda, a common household ingredient. The reaction between citric acid and baking soda is a classic example of a chemical reaction that produces carbon dioxide gas, water, and sodium citrate. In this article, we will answer some frequently asked questions about the reaction between citric acid and baking soda.
Q: What is the chemical equation for the reaction between citric acid and baking soda?
A: The chemical equation for the reaction between citric acid and baking soda is:
Q: What is the molar mass of citric acid and baking soda?
A: The molar mass of citric acid is 192.12 g/mol, and the molar mass of baking soda is 84.01 g/mol.
Q: How many moles of citric acid are in a 13.00 g sample?
A: To calculate the number of moles of citric acid, we need to divide the mass of citric acid by its molar mass:
Number of moles of citric acid = mass of citric acid / molar mass of citric acid = 13.00 g / 192.12 g/mol = 0.0677 mol
Q: How many moles of baking soda are required to react with 0.0677 mol of citric acid?
A: The chemical equation shows that 3 moles of baking soda react with 1 mole of citric acid. Therefore, the number of moles of baking soda required to react with 0.0677 mol of citric acid is:
Number of moles of baking soda = 3 x number of moles of citric acid = 3 x 0.0677 mol = 0.2031 mol
Q: What is the mass of baking soda required to react with 0.2031 mol of citric acid?
A: To calculate the mass of baking soda required to react with 0.2031 mol of citric acid, we need to multiply the number of moles of baking soda by its molar mass:
Mass of baking soda = number of moles of baking soda x molar mass of baking soda = 0.2031 mol x 84.01 g/mol = 17.15 g
Q: What are the products of the reaction between citric acid and baking soda?
A: The products of the reaction between citric acid and baking soda are carbon dioxide gas, water, and sodium citrate.
