CAUSTIC SODA

Caustic Soda, also known as sodium hydroxide (NaOH), is a highly versatile and essential chemical compound. It is one of the most widely used industrial chemicals globally, finding applications in various industries due to its potent alkaline properties. Caustic soda is manufactured through the electrolysis of sodium chloride (salt) solution, and its physical state is a white, solid, hygroscopic substance in the form of flakes, pellets, or granules.

KEY CHARACTERISTICS

Caustic soda possesses several distinctive properties that make it an indispensable compound in numerous industrial processes:

1. Highly Alkaline:  

   It is a strong base with a very high pH level, making it capable of neutralizing and reacting with acidic substances.

2. Solubility:  

   Caustic soda is highly soluble in water, and the resulting solution is strongly alkaline.

3. Hygroscopic:  

   It has a strong affinity for moisture, which means it readily absorbs water from the surrounding atmosphere.

4. Corrosive:  

   Caustic soda is highly corrosive to many materials, especially metals, and must be handled with care.
