Difference Between Sodium Carbonate and Sodium Bicarbonate
Sodium Carbonate Sodium Bicarbonate
Sodium carbonate is often referred to as soda ash or washing soda. Sodium bicarbonate is popularly called as baking soda.
Sodium carbonate comes with the chemical formula [latex]Na_{2}Co_{3}[/latex]. Sodium bicarbonate formula is given as [latex]NaHCo_{3}[/latex].
Sodium carbonate is made up of sodium and acid. Sodium bicarbonate comes with sodium, acid and hydrogen.
Sodium carbonate is diprotic and a strong base compound. When treated with acid it converts into sodium bicarbonate. It also functions as a good conductor of electricity. Sodium bicarbonate is a weaker base and is usually monoprotic.
Sodium carbonate is commonly used in neutralizing acidic solutions in various fields. Sodium bicarbonate is also used as a odor neutralizer, cleaning or exfoliating agent, and sometimes as a temporary fire extinguisher.
Sodium carbonate is used for body processes or reactions. Sodium bicarbonate is found in our body and is an important element. It helps to regulate and neutralize high acidity levels in the blood.
These are some differences between sodium carbonate and sodium bicarbonate. To know more about different chemical substances and other chemistry topics you can keep visiting BYJU’S or download our app for interesting content and learning experience.
