Chemical Properties and Common Uses of Sodium Bicarbonate

Common Industrial Uses and Products that Include Sodium Bicarbonate

Sodium bicarbonate, commonly known as baking soda, has a wide range of industrial applications. It is used as a leavening agent in the food industry, as well as a buffering agent in the pharmaceutical industry. Sodium bicarbonate is also used in the production of glass, ceramics, and detergents. In the textile industry, it is used as a cleaning and finishing agent for fabrics.

Some common products that include sodium bicarbonate are toothpaste, antacids, and baking powder. It is also used as an ingredient in some fire extinguishers, as it can help to smother flames by releasing carbon dioxide.

How Sodium Bicarbonate is Produced

Sodium bicarbonate is produced through a chemical reaction between sodium chloride, ammonia, and carbon dioxide. The process involves several steps, including the formation of ammonium bicarbonate, which is then decomposed to produce sodium bicarbonate.

The production of sodium bicarbonate can also be done through a Solvay process, which involves the reaction of sodium chloride with ammonia and carbon dioxide in a solution. The resulting product is then filtered and dried to produce sodium bicarbonate.

When Sodium Bicarbonate was First Discovered and Made Commercially Available

Sodium bicarbonate was first discovered by French chemist Nicolas Leblanc in 1791. However, it was not until the mid-19th century that it was produced on a large scale and made commercially available.

In the early 1840s, the American chemist Austin Church and his brother-in-law John Dwight began producing baking soda in New York. Their company, Church & Dwight, is still one of the leading producers of baking soda today.

Conclusion

Sodium bicarbonate is a versatile chemical that has a wide range of industrial applications. Its production involves a chemical reaction between sodium chloride, ammonia, and carbon dioxide, and it can also be produced through a Solvay process. Sodium bicarbonate was first discovered in 1791 by French chemist Nicolas Leblanc, but it was not until the mid-19th century that it was produced on a large scale and made commercially available. Today, it is used in a variety of products and industries, from toothpaste and antacids to glass and ceramics.
