Sodium bicarbonate chemical formula is:

Introduction of Sodium Bicarbonate:

Sodium bicarbonate is a white crystalline or powdered substance, which is chemically known as Sodium Hydrogen Carbonate, with the molecular formula NaHCO3.In nature, sodium bicarbonate is found mainly in natural minerals.

It has good stability and solubility, and can be dissolved in polar solvents such as water, methanol and ethanol, but not in non-polar solvents such as hexane and ethyl acetate. Sodium bicarbonate is chemically stable, but it decomposes during heating to produce sodium oxide and carbon dioxide.

Physical Properties of Sodium Bicarbonate:

Sodium bicarbonate is white crystal, or opaque monoclinic crystal system fine crystal. It is odorless, non-toxic, salty, soluble in water, slightly soluble in ethanol.

Chemical properties of sodium bicarbonate:

Stable chemical properties at room temperature, easy to decompose by heat, rapid decomposition above 50 ℃, no change in dry air, slow decomposition in humid air. It can react with both acid and alkali. It reacts with acid to produce corresponding salt, water and carbon dioxide, and reacts with alkali to produce corresponding carbonate and water.

Applications and precautions of sodium bicarbonate:

1, the application of sodium bicarbonate:

As a food additive: sodium bicarbonate can be used as a food additive to regulate the pH of the food, and to increase the fluffiness and texture of the food. Used in the manufacture of cosmetics and detergents: Sodium bicarbonate can be used in the manufacture of cosmetics and detergents, with the effect of decontamination, removing odor and adjusting pH value.

Used in medicine: Sodium bicarbonate can be used in medicine as drug neutralizer, lubricant and antacid. Used in industrial field: Sodium bicarbonate can also be used in industrial field, as raw material for manufacturing glass and ceramics, as well as regulating water quality and sewage treatment agent.

2, precautions:

Sodium bicarbonate is highly corrosive, you need to wear gloves and protective glasses when using it, and pay attention to avoid contact with skin, eyes and so on. At the same time, sodium bicarbonate should not be mixed with acidic substances to avoid the production of dangerous gases.
