Caustic Soda, also known as Sodium Hydroxide (NaOH), is a highly caustic and versatile chemical used in a wide range of industries. ⸻ Chemical Details: • Chemical Formula: NaOH • Molar Mass: 40.00 g/mol • Appearance: White pellets, flakes, or solid blocks • Solubility: Highly soluble in water, exothermic reaction • pH (1% solution): Very high (strongly alkaline) ⸻ Applications: • Chemical Manufacturing: Used in making soaps, detergents, and synthetic fabrics • Water Treatment: pH regulation, sludge removal • Petroleum Industry: Refining of petroleum products • Food Industry: Peeling fruits/vegetables, cocoa processing (regulated use) ⸻ Safety & Handling: • Extremely corrosive — can cause severe burns • Must wear gloves, goggles, and protective clothing when handling • Store in airtight containers to avoid reaction with moisture and CO₂

Sodium sulfite (Na2SO3) is an inorganic salt, a white, water-soluble solid with reducing properties. It's used as a food preservative, antioxidant, and oxygen scavenger in various applications, including food processing, pharmaceuticals, and industrial processes. Key Properties and Uses:

• Chemical Formula: Na2SO3 
• Appearance: White, crystalline powder or solid 
• Solubility: Soluble in water 
• Reducing Agent: Possesses reducing properties, making it useful in various applications 
• Food Preservative: Prevents discoloration and spoilage in dried fruits, vegetables, and seafood. 
• Antioxidant: Inhibits oxidation reactions in food and other products. 
• Oxygen Scavenger: Used in low-pressure boilers to remove dissolved oxygen and prevent corrosion. 
• Other Uses: Used in the manufacture of detergents, pharmaceuticals, and as a fixing agent in photography. 
• Food Grade: Specifically used as a food preservative in fruits, vegetables, and seafood, as well as in starch and sweetener production. 
• Safety: Considered safe for most people when used as directed, but individuals with sensitivities or allergies should exercise caution.
