What is the caustic solution?
Caustic soda is one of the common names for sodium hydroxide (NaOH), which is also known as lye. Its common name derives from its chemical identity as a sodium hydrate and because it is caustic or corrosive. In pure form, caustic soda is a waxy, white solid. It readily absorbs water and forms aqueous solutions.
What does caustic contain?
Sodium hydroxide (NaOH), also known as caustic soda or lye, is a highly versatile substance used in a variety of manufacturing processes. Sodium hydroxide is a co-product of chlorine production.
What are the hazards associated with sodium hydroxide solution?
Contact with very high concentrations of sodium hydroxide can cause severe burns to the eyes, skin, digestive system or lungs, resulting in permanent damage or death. Prolonged or repeated skin contact may cause dermatitis. Repeated inhalation of sodium hydroxide vapor can lead to permanent lung damage.

What is caustic in chemistry?
a : a substance that burns or destroys organic tissue by chemical action. b : a strong corrosive alkali (such as sodium hydroxide)
How do you make a caustic solution?
Stir the sodium hydroxide, a little at a time, into a large volume of water and then dilute the solution to make one liter. Add sodium hydroxide to water—do not add water to solid sodium hydroxide.

What is caustic soda used for?
Caustic soda (sodium hydroxide) is a versatile alkali. Its main uses are in the manufacture of pulp and paper, alumina, soap and detergents, petroleum products and chemical production. Other applications include water treatment, food, textiles, metal processing, mining, glass making and others.
How do you determine the strength of caustic solution?
The typical method to determine the strength is to take a titration of a sample of the used solution with an acid of known concentration e.g. Sulfuric or Hydrochloric Acid, using Phenolphthalein as an indicator.
What is caustic expression?
Use the adjective caustic to describe any chemical that is able to burn living tissue or other substances, or, figuratively, a statement that has a similarly burning effect. Caustic in this sense means harshly critical. In the figurative sense, near synonyms are biting, scathing, and sarcastic.
What are the characteristics of caustic solutions?
The most obvious characteristic of caustic solutions is the decrease of interfacial tension and its effect on recovery efficiency.
Is caustic soda regulated by the dot?
Liquid caustic soda is regulated by the U.S. Department of Transportation (DOT) and is classified as a corrosive material, with the DOT identification number UN 1824. Caustic soda solution, also known or referred to as Sodium Hydroxide, Lye, or Potassium Hydroxide, and is a very corrosive industrial chemical.
Soda Ash Replacement- Caustic soda can be used interchangeably for many applications in glass, paper, pulp, phosphates and silicates industries. Renewable Fuels- Caustic soda is used for pH adjustment and formation of in situ sodium methylate in bioethanol and biodiesel processing.
What is caustic acid and why is it dangerous?
Caustic is a strong irritant and corrosive to the skin, eyes, respiratory tract, as well as, gastrointestinal system if ingested. Personal Protective Equipment (PPE) is required to reduce and hopefully eliminate potential health risks.
