Chemical properties:
Sodium hydroxide solution has all the chemical properties of a soluble base.
- a) Change the color of the thread
- Sodium hydroxide solution does:
- + Change litmus color to blue
- + Change the color of phenolphthalein solution from colorless to red
- Sodium hydroxide solution does:
- b) Reaction with acids
- Sodium hydroxide solution reacts with acid to form salt and water.
- Sodium hydroxide + HCl → NaCl + H2O
- 3Sodium hydroxide + H3PO4 → Na3PO4 + 3H2O
- Sodium hydroxide solution reacts with acid to form salt and water.
- c) Reaction with acidic oxides
- Sodium hydroxide solution reacts with acid oxide to form salt and water.
- 2Sodium hydroxide + CO2 → Na2CO3 + H2O
- 2Sodium hydroxide + SO2 → Na2SO3 + H2O
- Sodium hydroxide solution reacts with acid oxide to form salt and water.
- d) Reaction with salt
- Sodium hydroxide solution reacts with some salts to form new salts and new bases.
- 2Sodium hydroxide + Cu(NO3)2 → Cu(OH)2 ↓ + NaNO3
- 2Sodium hydroxide + FeSO4 → Fe(OH)2 ↓ + Na2SO4
- Sodium hydroxide solution reacts with some salts to form new salts and new bases.

MAIN APPLICATIONS OF SODIUM HYDROXIDE IN INDUSTRY
In the chemical cleaning industry:
participated in the preparation of Sodium Hypochlorite, also known as Javen, a bleaching agent.
Sodium hydroxide and sodium compounds are important ingredients in the production of laundry detergents. Sodium
Hydroxide will hydrolyze fats in animal and vegetable oils to make soap.
More simply, it is mixed with hot water to create a sodium hydroxide solution that cleans technological equipment, tanks, drain pipes under sinks and drains, etc.
Sodium hydroxide solution can effectively dissolve grease and fat. Soaking stainless steel and glass in caustic soda is an excellent degreasing solution. It is also a common ingredient in oven cleaners.
In addition, in the production of detergents for washing machines, Sodium hydroxide has the most positive effect. It has the effect of surface cleaning, rust inhibitors and defoamers. The detergent solution containing caustic soda for washing machines is said to be more environmentally friendly.
Sodium hydroxide is also used in households as a drain cleaner, usually in powder or concentrated liquid gel form. It breaks down water-soluble fats. In addition, you can refer to how to preparation of NaOH in industrial applications here.
- In the pharmaceutical industry:
- Manufacture or sell products containing sodium such as: Sodium phenolate, an ingredient of Aspirin pain reliever, medical disinfectant, etc.
- In the paper industry
- Sodium hydroxide is used as a chemical to treat wood, bamboo, rattan, etc. to produce paper using the Sulfate and Soda method.
- In the production of artificial fibers
- Sodium hydroxide is effective in breaking down toxic byproducts specifically lignin - a harmful substance that comes along with cellulose found in wood pulp.
- In the textile dyeing industry
- Sodium hydroxide decomposes pectins and waxes during the treatment of raw fabrics, increasing the gloss and color absorption of dyed fabrics.
- In the oil and gas industry
- pH adjustment of drilling fluids…removal of sulfides, sulfide compounds and acid compounds in petroleum refining.
- In the food processing industry
- Remove fatty acids in the process of refining vegetable and animal oils before using them in food production. In addition, Sodium hydroxide is used to prepare solutions for cleaning bottles and equipment in beer factories. Prepare chemicals to treat vegetables and fruits before processing or canning...
- In water treatment industry
- + Adjusts pH and regenerates ion exchange resin. Also used to neutralize and descale pipes.
- + In addition, it is also used in some hair straightening creams. However, due to the high burning ability and intensity of Sodium hydroxide, it is mainly used by experts, hair straightening cream manufacturers often use other alkaline chemicals that are safer for consumers.
Cleaning swimming pool with NaOH solution
The fabric is dyed after being bleached with NaOH solution.
