Sodium Hydroxide (NaOH), commonly known as caustic soda, is a highly corrosive, strong alkali widely used in industrial, chemical, and manufacturing processes. It is known for its strong alkalinity, high reactivity, and effectiveness in neutralization and chemical synthesis.
Chemical & Physical PropertiesChemical Formula: NaOH
Molecular Weight: 40.00 g/mol
Appearance: White, odorless solid (flakes, pellets, or granules) or colorless liquid (solution form)
Odor: Odorless
Solubility: Highly soluble in water (exothermic reaction)
pH: Strongly alkaline
Flammability: Non-flammable
Reactivity: Reacts violently with acids; absorbs moisture and carbon dioxide from air
Chemical Manufacturing: Used in the production of soaps, detergents, dyes, and inorganic chemicals
pH Regulation: Used for neutralization and pH control in various chemical processes
Pulp Processing: Essential for pulping and bleaching processes in paper manufacturing
Mercerization: Used to improve strength, luster, and dye affinity of cotton fabrics
pH Adjustment: Used in municipal and industrial water treatment plants
Effluent Treatment: Neutralizes acidic wastewater
Food Processing: Used for cleaning, peeling, and processing food products (food-grade NaOH)
