Caustic soda, also known as sodium hydroxide (NaOH), is a highly versatile and widely used chemical compound. When in liquid form at a concentration of 50%, it is commonly referred to as caustic soda liquid 50%. Here's a detailed overview along with its CAS number:

 1. Chemical Name: Caustic Soda Liquid 50%

2. Common Names: Sodium Hydroxide Solution, Lye

3. Chemical Formula: NaOH

4. CAS Number: 1310-73-2

5. Molecular Weight: Approximately 40.00 g/mol

6. Appearance: Caustic soda liquid 50% is a clear, colorless liquid with a slippery feel and a characteristic odor.

7. Concentration: Caustic soda liquid 50% refers to a solution of sodium hydroxide in water, where the concentration of sodium hydroxide is 50% by weight.

 8. Physical Properties:

   - Density: The density of caustic soda liquid 50% is approximately 1.52 g/cm³.

   - Boiling Point: The boiling point of caustic soda liquid 50% is approximately 139°C (282°F) at atmospheric pressure.

   - Solubility: Caustic soda is highly soluble in water, and its solubility increases with temperature.

 9. Production:

   - Caustic soda liquid 50% is typically produced through the electrolysis of aqueous sodium chloride (brine) in a process called the chlor-alkali process.

   - In this process, sodium hydroxide is produced at the cathode (negative electrode) and chlorine gas is produced at the anode (positive electrode).

    - Petroleum Industry: It is used in refining petroleum products, such as in the production of gasoline, diesel, and lubricants.

    - Pulp and Paper Industry: Caustic soda is used in the pulping and bleaching processes of papermaking to dissolve lignin and remove color from pulp.

    - Textile Industry: It is used in textile processing, such as in the mercerization of cotton fibers to improve strength and dye uptake.

    - Water Treatment: Caustic soda is used in water treatment processes for pH adjustment, neutralization of acidic wastewater, and removal of heavy metals through precipitation reactions.

    - Cleaning and Degreasing: It is used as a strong alkaline cleaner and degreaser in industrial cleaning applications.

 11. Safety:

    - Caustic soda is a corrosive substance that can cause severe burns to the skin, eyes, and respiratory tract upon contact.

    - Proper handling procedures, including the use of gloves, goggles, and protective clothing, should be followed when working with caustic soda liquid 50%.

    - Spills should be promptly cleaned up using neutralizing agents and appropriate safety equipment.

    - Inhalation of caustic soda vapors should be avoided, and adequate ventilation should be provided in areas where caustic soda is used or stored.
