Which of the following is the chemical name for common baking soda?
Sodium carbonate
Sodium bicarbonate
Calcium hydroxide
Sodium chloride
Sodium bicarbonate
Sodium bicarbonate, commonly known as baking soda, is a chemical compound with the formula NaHCO3тАЛ. It is a white crystalline solid composed of sodium ions and bicarbonate ions, widely used as a leavening agent in cooking and as a mild antacid in medicine.

NaHCO3тАЛ тАФ Chemical formula for sodium bicarbonate
2NaHCO3тАЛ╬ФтАЛNa2тАЛCO3тАЛ+H2тАЛO+CO2тАЛ тАФ Thermal decomposition of baking soda
When baking soda is heated or comes into contact with an acidic medium, it undergoes a reaction that releases carbon dioxide (CO2тАЛ) gas. In baking, this liberated gas gets trapped within the dough or batter matrix, causing it to expand and rise.
It is a weak base that reacts with acids to produce carbon dioxide gas and water.
It has an amphoteric nature, reacting with both acids and bases.
Provides quick leavening without the fermentation time required by yeast.
Neutralizes stomach acidity rapidly for quick heartburn relief.
Excessive use can leave a bitter, soapy taste due to the accumulation of alkaline sodium carbonate residues.
Food industry as a baking powder component and leavening agent
Pharmaceuticals as an antacid for indigestion
Dry chemical fire extinguishers
Sodium carbonate (Na2тАЛCO3тАЛ) is known as washing soda.
Option A is sodium carbonate, Option C is calcium hydroxide (slaked lime), and Option D is sodium chloride (table salt).
B is correct тАФ Sodium bicarbonate is the chemical name for common baking soda.
For railway and technical exams like RRBJE, carefully differentiate between baking soda (NaHCO3тАЛ) and washing soda (Na2тАЛCO3тАЛcdot10H2тАЛO) as questions frequently swap their chemical names and formulas.
