What is Caustic Soda (Sodium Hydroxide – NaOH)?

Caustic Soda, chemically known as Sodium Hydroxide (NaOH), is a highly alkaline, inorganic compound widely used as a fundamental raw material in numerous industrial processes. It is produced through the chlor-alkali process, where sodium chloride (brine) is electrolyzed using modern membrane cell technology to yield sodium hydroxide, chlorine, and hydrogen.

Due to its strong alkalinity, Caustic Soda is essential for neutralizing acids, breaking down organic materials, adjusting pH levels, and driving chemical reactions across multiple industries.

Key Physical and Chemical Properties of Caustic Soda

• Chemical Formula: NaOH
• Appearance: White solid (flakes or pearls) or clear liquid (solution)
• pH Value: 13–14 (strong alkali)
• Solubility: Completely soluble in water (exothermic reaction)
• Hygroscopic Nature: Absorbs moisture and CO₂ from air
• Production Method: Membrane cell chlor-alkali process
