Sodium Bicarbonate

Synonyms: baking soda, drinking soda, edible soda, bicarbonate of soda, sodium hydrocarbonate

Chemical formula: NaHCO3

International name: SODIUM BICARBONATE

Grade: import, pure, GOST 4201-79

Appearance: white powder

Sodium bicarbonate (bicarbonate of soda, sodium hydrocarbonate) NaHCO3 (other names: baking soda, edible soda) is acid sodium salt of carbonic acid as a fine white powder.

Sodium bicarbonate enters into a reaction with acids forming salt and carbonic acid that immediately disintegrates into carbon dioxide and water:

NaHCO3 + HCl → NaCl + H2CO3

H2CO3 → H2O + CO2↑

In cooking, the following reaction with acetic acid followed by forming sodium acetate occurs: NaHCO3 + CH3COOH → CH3COONa + H2O + CO2↑

Application of sodium bicarbonate

Sodium bicarbonate (hydrocarbonate of sodium) is used as follows:

· in chemical industry, for production of dyers, foamed plastics and other organic products, fluoride reagents, household chemicals, fillers for fire extinguishers, for separation of carbon dioxide, hydrogen sulphide from gas mixtures,

· in non-ferrous industry,

· in consumer industry, in production of sole rubbers and artificial leathers, leather production (skin tanning and neutralization), textile industry (finishing of silk and cotton fabrics),

· in medicinal and pharmaceutical industries,

· in food industry, as food additive E500, in bread making, in confectionery production, beverage preparation, etc.
