Sodium persulfate (Na₂S₂O₈) is a white crystalline solid widely used as a strong oxidizing agent in various industrial applications. In India, while there isn't a specific Indian Standard (IS) exclusively for sodium persulfate, its usage and quality are often aligned with international standards and industry practices.

Physical and Chemical Properties:

• Molecular Formula: Na₂S₂O₈
• Molecular Weight: 238.10 g/mol
• Appearance: White crystalline powder
• Solubility: Highly soluble in water
• Decomposition: Releases oxygen and heat upon decomposition

Industrial Applications:

• Polymerization Initiator: Utilized in the polymer industry to initiate the polymerization of monomers.
• Textile Industry: Employed as a bleaching agent and for dye fixation.
• Electronics Cleaning: Used in cleaning and etching printed circuit boards.
• Cosmetics: Incorporated in formulations for hair bleaching and hair dyeing products.

Safety and Handling:

Sodium persulfate is a strong oxidizer and should be handled with care. It can cause skin and respiratory irritation upon contact or inhalation. Proper personal protective equipment, such as gloves and masks, is recommended during handling. It should be stored in a cool, dry place, away from organic materials and reducing agents to prevent hazardous reactions.

Availability in India:

Sodium persulfate is available through various chemical suppliers and distributors across India. The quality and specifications may vary depending on the manufacturer. For procurement, it's advisable to consult with reputable suppliers to ensure the product meets the required standards for your specific application.

For detailed information on quality specifications and regulatory compliance, referring to the supplier's product data sheet and safety data sheet is recommended.

Calcium sulfide (CaS) is an inorganic compound characterized by its white crystalline appearance and notable reactivity. It crystallizes in a cubic structure similar to rock salt.

 

Physical and Chemical Properties:

• Molecular Formula: CaS
• Molecular Weight: 72.14 g/mol
• Appearance: White crystalline solid
• Density: 2.59 g/cm³
• Melting Point: >2000°C
• Solubility: Slightly soluble in cold water; more soluble in hot water with partial decomposition; insoluble in alcohol

Production:

Calcium sulfide is typically produced through the carbothermic reduction of calcium sulfate (CaSO₄) using carbon sources like charcoal:

CaSO₄ + 2 C → CaS + 2 CO₂

This reaction reduces calcium sulfate to calcium sulfide, releasing carbon dioxide in the process.

 

Reactivity and Applications:

• Hydrolysis: In the presence of moisture, calcium sulfide hydrolyzes, releasing hydrogen sulfide (H₂S), which has a characteristic odor of rotten eggs.
• Desulfurization: Employed as a desulfurizing agent in industrial processes to remove sulfur compounds from flue gases, thereby reducing air pollution.
• Chemical Synthesis: Serves as a source of sulfide ions in chemical reactions and organic synthesis, aiding in the preparation of various sulfur-containing compounds.
• Phosphorescence: Exhibits phosphorescent properties, glowing red for up to an hour after exposure to light, making it useful in certain luminescent applications.

Safety and Handling:

Due to its reactivity, especially its tendency to release toxic hydrogen sulfide gas upon contact with acids or moisture, calcium sulfide should be handled with caution. Proper protective equipment, such as gloves and eye protection, is recommended, and it should be stored in a dry, well-ventilated area away from acids and moisture sources.

Natural Occurrence:

In nature, calcium sulfide is found as the mineral oldhamite, which is a rare component in some meteorites and has significance in solar nebula research.
