Soda is mainly used in the production of glass, such as flat glass, bottle glass, optical glass and high-grade ware; in the chemical industry, soda is used in the production of sodium salts, metal carbonates, bleach, fillers, detergents, catalysts and dyes.

In the metallurgical industry, soda is used to remove sulfur and phosphorus, for ore dressing and the production of copper, lead, nickel, tin, uranium, aluminum and other metals; in the ceramics industry, soda is used to produce refractory materials and glaze. In addition, industrial gas desulfurization, industrial water treatment, metal degreasing, cellulose and paper production, soap manufacturing, etc. also need soda.

Soda can be used directly as a raw material in the pharmaceutical industry. Soda can also be used in film production, tanning, mineral processing, smelting, metal heat treatment, as well as for fiber, rubber industry. Soda is also used as wool detergent, foam fire extinguishing agent, as well as used in agriculture to soak seeds and so on. It is used in the production of acid and alkali fire extinguishers and foam fire extinguishers in fire-fighting equipment.

Extended information:

Consumption is distinct from industrial alkalis such as soda ash (sodium carbonate) and baking soda (sodium bicarbonate), which is made from a solution or crystals of soda ash after absorbing carbon dioxide. Therefore, baking soda is also known as edible soda (in powdered form) in some places. Baking soda is in solid state, round, white in color and soluble in water.

Single salts are divided into: normal salts, acid salts, and alkaline salts. Sodium bicarbonate is an acid salt produced by neutralizing a strong base with a weak acid, and is weakly alkaline when dissolved in water.

In mass production of steamed buns, doughnuts and other foods, often baking soda melt water into the noodles, hot decomposition into sodium carbonate, carbon dioxide and water, carbon dioxide and water vapor overflow, can lead to more fluffy food, sodium carbonate residue in the food. Buns with excessive amounts of baking soda can be tasted.
