What is the chemical formula of Baking Soda?
Na2тАЛCO3тАЛ
NaHCO3тАЛ
NaOH
NaCl
NaHCO3тАЛ
Baking soda is chemically known as Sodium Bicarbonate, represented by the formula NaHCO3тАЛ. It is an amphoteric compound that acts as a mild base and is a common ingredient in baking and fire extinguishing compositions.
Baking soda is chemically known as Sodium Bicarbonate, represented by the formula NaHCO3тАЛ. It is an amphoteric compound that acts as a mild base and is a common ingredient in baking and fire extinguishing compositions.
Think of baking soda like a tiny internal engine inside a cake; when it feels the heat, it releases gas 'exhaust' that pushes the batter up to make it fluffy.
Remember 'Bicarbonate for Baking': Both start with 'Bi-'.
NaHCO3тАЛ тАФ Chemical formula of Sodium Bicarbonate
2NaHCO3тАЛтЖТNa2тАЛCO3тАЛ+H2тАЛO+CO2тАЛ тАФ Thermal decomposition reaction
When heated or reacted with an acid, baking soda undergoes thermal decomposition to release carbon dioxide gas: 2NaHCO3тАЛ╬ФтАЛNa2тАЛCO3тАЛ+H2тАЛO+CO2тАЛтЖС. This release of CO2тАЛ bubbles creates air pockets in dough, causing it to rise during baking.
Sodium bicarbonate is also known as bicarbonate of soda.
It has an alkaline pH and acts as a leavening agent.
It reacts with acids to produce salt, water, and carbon dioxide gas.
Acts as an effective leavening agent for baking
Useful for neutralizing acidic spills
Effective in treating minor heartburn (antacid)
Can leave a soapy aftertaste if used in excess
Requires an acidic ingredient (like vinegar or lemon juice) to activate fully in recipes
Leavening agent in baking industry
Fire extinguisher component for grease/electrical fires
Common name for Na2тАЛCO3тАЛ is Washing Soda (Sodium Carbonate decahydrate).
Option A (Na2тАЛCO3тАЛ) is Washing Soda, Option C (NaOH) is Caustic Soda (Sodium Hydroxide), and Option D (Na┬аCl) is common table salt.
B is correct тАФ Sodium bicarbonate is represented by the chemical formula NaHCO3тАЛ.
In competitive exams, always distinguish between 'Washing Soda' (Na2тАЛCO3тАЛтЛЕ10H2тАЛO) and 'Baking Soda' (NaHCO3тАЛ); the presence of the 'H' atom (Hydrogen) in the formula is the key identifier for the bicarbonate group.
