Sodium Carbonate vs. Sodium Bicarbonate: Know the Difference
By Shumaila Saeed || Published on January 8, 2024
Sodium Carbonate is a stronger base used in glassmaking and detergents, while Sodium Bicarbonate, a mild base, is used in baking and as an antacid.
Key Differences
Sodium Carbonate (Na2CO3), also known as washing soda or soda ash, is an alkaline compound with a high pH. Sodium Bicarbonate (NaHCO3), commonly known as baking soda, has a lower pH and acts as a milder base.
