Participates in the production of various paints and varnishes. In the food industry, it is marked with the E500 code and is used as an emulsifier, acidity regulator and baking powder. The composition of soda ash allows it to be used directly as a detergent, as it perfectly removes fat, neutralizes the acidic environment and softens water. Soda ash (formula - Na 2 CO 3 ) is a crystalline powder, odorless and colorless. It is hygroscopic and dissolves well in water when heated. The resulting solution is characterized by a strong alkaline reaction.

SCOPE OF CARBAMIDE (UREA) Urea is the most widely used in agriculture. Due to its high nitrogen content (about 46%), urea is used as a nitrogen fertilizer. In the chemical industry, urea is used for the synthesis of urea-aldehyde and urea-formaldehyde resins, which are necessary for the production of fiberboard. Carbamide is also used to clean nitrogen oxides from internal combustion engines, flue gases and incineration plants. GOST 2081-92 carbamide is a colorless crystal that does not have any odor. Urea is very soluble in water and other polar solvents. The reaction of urea is due to the fact that both nitrogen atoms are nucleophiles, which contributes to the formation of salts when interacting with strong acids. Alcohol is used to displace ammonia from urea. In this case, urethanes are formed. The advantage of using urea (the composition of CO (NH 2 ) 2 ) is its affordable cost, the possibility of large-scale synthesis from inorganic compounds and a high nitrogen content.
