Features of Caustic Soda
Sodium hydroxide is widely used in various production processes. In chemical production, sodium hydroxide provides an alkaline environment or as a catalyst. A dilute solution of NaOH can be used as a washing liquid when it is used at home. In food production, sodium hydroxide is sometimes used to process food. Sodium hydroxide is even a necessary seasoning for a famous dish. Note that the use of sodium hydroxide is strictly controlled at this time; some illegal traders will use sodium hydroxide in excess to make the food more "good", but such food can cause disease.
As for the difference between the base of the base and the caustic soda, the base is divided into a solid and a liquid according to its form, and the solid has a block, a sheet (salt alkali), a rod, and a granular shape, wherein the granular form is the base, and the purity is generally higher, and the price is higher. expensive. Caustic soda is often referred to as block and flake, and is actually sodium hydroxide.

Application of Caustic Soda
Widely used sewage treatment agent, basic analytical reagent, standard lye for analytical analysis, small amount of carbon dioxide and moisture absorbent, and acid neutralized sodium salt. Manufacture of other reagents containing hydroxide ions; important applications in papermaking, printing and dyeing, wastewater treatment, electroplating, and chemical drilling etc.
Store in a cool, dry place in a sealed package. It is divided into storage and transportation with acid, ammonium and easy (combustible).
Do not touch the skin. If the skin (eyes) is in contact, rinse with running water and apply a boric acid solution.
If you eat too much, rinse your mouth with water, drink milk or egg white (such as acidic and harmless food) and seek medical attention immediately.
