What is the difference between soda ash and caustic soda?

Soda and soda are different in physical and chemical properties and uses. Soda belongs to salt, and soda is a strong corrosive alkali. Soda soda is one of the important chemical raw materials, and it is widely used.

1. What's the difference between a name and a chemical formula?

(1) soda is: sodium carboNate, chemical formula na? CO? . ?

(2) Caustic soda is sodium hydroxide with the chemical formula of NaOH.

Second, the difference between physical and chemical properties:

(1) Soda: It belongs to salt. Sodium carbonate containing decahydrate is colorless crystal, unstable and easily weathered. It becomes white powder na2co 3. Na2CO3 is a strong electrolyte, which has the universality and thermal stability of salt, is easily soluble in water, and its aqueous solution is alkaline.

(2) Caustic soda: It is a strongly corrosive alkali, generally in flake or granular form, easily soluble in water (it will give off heat when dissolved in water) and form an alkaline solution, easily deliquescent and easily absorb water vapor in the air.

Third, the difference in use:

(1) Soda Soda: It is one of the important chemical raw materials, used to make chemicals, cleaning agents, detergents, photography and medicines.

(2) Caustic soda: widely used. It is used in papermaking, soap, dyes, rayon, aluminum production, petroleum refining, cotton fabric finishing, coal tar product purification, food processing, wood processing and machinery industry.
