Sodium Carbonate	Sodium Bicarbonate
Sodium carbonate is referred to as soda ash or washing soda.	Sodium bicarbonate is popularly called baking soda.
Sodium carbonate comes with the chemical formula Na2CO3.Na2Co3	The sodium bicarbonate formula is given as NaHCO3.NaHCo3
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 an odour 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.
