What are the essential differences between soda ash and caustic soda

Although soda ash and flake caustic soda are the same substance, they are still different. The aqueous solution of flake caustic soda has astringent taste and broad and delicate feeling. The solution is strong alkaline and has all the common molecular weight of alkali. The shape of flake caustic soda is white translucent flake solid. Flake caustic soda is a basic chemical raw material and is widely used in papermaking, synthetic washing, soap and viscose fiber, rayon and cotton fabrics and other light and textile industry, pesticide, dye, rubber and chemical industry, oil drilling, refining oil oil and oil and tar refining, as well as national defense industry, machinery industry, wood processing, metallurgy industry, pharmaceutical industry and urban construction, etc., also used in the manufacture of chemicals, paper, soap and detergent, rayon and cellophane, processing bauxite to make alumina, also used in textile mercerizing, water treatment, etc.

Soda ash is sodium carbonate, flake caustic soda and caustic soda are sodium hydroxide, and the relative density (water = 1) is 2.532 caustic soda. Fake caustic soda is sodium hydroxide. NaOH is a strong alkali. The melting point of sodium hydroxide production process. White powder or fine particles form crystals (anhydrous pure products). Sodium hydroxide solid dissolves in water and releases heat. Also known as caustic soda, caustic soda and sodium hydroxide are common strong alkaloids, the degree of ablation increases with the increase of temperature, and a large amount of heat can be released when the ablation is saturated and the liquid concentration of the solution can reach 26.4mol/L(1:1).
