Sodium carbonate is a widely used chemical compound with the chemical formula Na2CO3, also known as soda ash. It is a white, water-soluble solid that has strong alkaline properties. Sodium carbonate is produced in two ways: natural and industrial. In the natural method, this chemical is extracted from the Trona mines, and in the industrial method, the Solvay process is used, in which ammonia, carbon dioxide, and water react with sodium chloride. Sodium carbonate is used in various industries such as glass production, soap and detergents, pH adjustment in chemical processes, water purification, and the food industry.

Environmental impact of Sodium Carbonate
Sodium carbonate is generally considered a low-hazard substance for the environment, but if discharged improperly and in large quantities, it can harm aquatic and terrestrial ecosystems. The entry of this substance into water sources may increase the pH of the water and make it alkaline, which can disrupt the life of aquatic organisms. Also, the accumulation of sodium carbonate in the soil may reduce the chemical balance of the soil and harm plant growth. To avoid negative effects, the disposal of this substance must be carried out in compliance with environmental regulations.
Safety Measures and Regulations for Handling Sodium Carbonate
Sodium carbonate, although relatively safe, can cause irritation in contact with the skin and eyes, and inhalation of its dust may lead to respiratory problems. When working with this substance, the use of personal protective equipment such as gloves, safety glasses and a mask is recommended. The work environment should be well ventilated to prevent dust accumulation. This substance should be stored in tight, dry containers and away from acidic substances. If sodium carbonate is spilled or spread, it must be carefully collected and disposed of in authorized locations to reduce potential hazards.
