The chemical formula for baking soda is NaHCO₃. More conventionally, it is called baking soda, and we can use baking soda as a leavening agent in baking and in many other ways, such as cleaning, deodorizing, and performing some medical treatments.

Physical Properties of Sodium Bicarbonate

Room Temperature State: Solid, usually white crystalline powder

Color: White

Odor: Odorless

Density: About 2.20 g/cm³

Melting Point: Decomposes at 270°C or 518°F

Boiling Point: It does not have any definite boiling point; on heating, it decomposes into sodium carbonate, water, and carbon dioxide.

Solubility in Water: Water-soluble-at about 9.6 g/100 mL at 20°C

Solubility in organic solvents: Insoluble

These properties reveal its nature as a solid with a crystalline appearance and water solubility.

Chemical properties of Sodium Bicarbonate

Reaction with Acids: Sodium bicarbonate reacts with acids to form carbon dioxide (CO₂), water (H₂O), and salt. With hydrochloric acid (HCl)

Decomposition upon Heating: On heating, sodium bicarbonate decomposes into sodium carbonate (Na₂CO₃), water, and carbon dioxide

Reaction with Bases: It reacts with strong bases to form carbonates and water.

Reaction with Water: In solution, it can act as a weak base and partially dissociate.

Application of Sodium Bicarbonate

Baking: This is used as a leavening agent in baking to make goods rise.

Cleaning: This chemical is used in home cleaning products as a mild abrasive combined with deodorizing properties.

Acid-Base Neutralization: This is commercially utilized by antacids to neutralize excess stomach acid and to adjust pH in many cases.

Fire Extinguishers: Some fire extinguishers use these to extinguish grease and electrical fires.

Medical Uses: This medication is used to treat metabolic acidosis, certain kidney diseases, and drug intoxication. It is also used as a mild antiseptic.

Personal Care: toothpaste and deodorants contain fragrance neutralizers.

Conclusion

With that, NaHCO3 is one of those versatile compounds serving various fields of purpose. It acts as a leavening agent in bakeries, for cleaning and deodorizing, as an acid neutralizer, and finds applications in fire extinguishers, medicine treatments, and even personal hygiene. Its multifunctional properties make it very essential not only in everyday applications but also in some industrial processes.
