Sodium bicarbonate is commonly known as baking soda.

Sodium bicarbonate is stable at room temperature, easily decomposed by heat, decomposes rapidly above 50°C, loses carbon dioxide completely at 270°C, remains unchanged in dry air, and decomposes slowly in moist air.

Sodium bicarbonate can react with both acids and bases. Sodium bicarbonate reacts with acid to produce the corresponding salt, water and carbon dioxide, and reacts with alkali to produce the corresponding carbonate and water. In addition to this, it can react with certain salts and undergo double hydrolysis with aluminum chloride and aluminum chlorate to produce aluminum hydroxide, sodium salt and carbon dioxide.

Uses of sodium bicarbonate:

In food processing, it is one of the most widely used loosening agents for the production of cookies, bread, etc., and is the carbon dioxide generating agent in fizzy drinks; it can be compounded with alum as alkaline baking powder, or compounded with soda ash as civil litharge; and it can be used as a preservative for butter.

Sodium bicarbonate is non-dangerous, but should be prevented from moisture. It should be stored in dry and ventilated warehouse. It should not be mixed with acids for storage and transportation. Edible baking soda must be especially careful not to be mixed with toxic substances storage and transportation to prevent contamination.
