Sodium Carbonate vs. Sodium Bicarbonate: What's the Difference?
Edited by Janet White || By Harlon Moss || Published on November 21, 2023
Sodium carbonate (Na2CO3) is a strong base used in laundry detergents. Sodium bicarbonate (NaHCO3), also known as baking soda, is a mild base used in baking.
Key Differences
Sodium carbonate (Na2CO3), also known as soda ash or washing soda, is a strong alkaline compound. Sodium bicarbonate (NaHCO3), commonly known as baking soda, is a milder base. While both compounds contain sodium and carbonate ions, sodium bicarbonate also includes a hydrogen atom.
Sodium carbonate is widely used in laundry detergents, water softening, and glass manufacturing due to its strong alkaline nature. Sodium bicarbonate, being milder, is used in baking as a leavening agent, for neutralizing acids, and in fire extinguishers.
Sodium carbonate has a higher pH and is more caustic, making it effective for heavy-duty cleaning and industrial processes. Sodium bicarbonate, with a lower pH, is safer for cooking and household cleaning, as it is less corrosive.
Due to its stronger alkalinity, sodium carbonate requires more caution in handling, as it can be more irritating to skin and eyes. Sodium bicarbonate is widely used in personal care products and is generally considered safe for consumption and use in homes.
Both compounds are derived from natural sources: sodium carbonate is often obtained from trona ore or processed from salt and limestone, while sodium bicarbonate can be produced through chemical reactions involving sodium carbonate.
