Soda Ash Light:
IUPAC Name: Disodium carbonate|
HS Code: 2836.20.00
Formula: Na2CO3
Appearance: White Crystal Powder
CAS No: 497-19-8
Common Names: Soda Ash Light
Soda ash light, also called anhydrous sodium carbonate, is a white, odorless granular powder that is soluble in water and forms a strongly alkaline aqueous solution. It is also hygroscopic and absorbs moisture from the atmosphere, causing it to clump together.
It is mainly used in Detergent Industry acting as a water softener, and competes with the magnesium and calcium ions in hard water, preventing them from combining with the detergent used. In addition, it also helps to remove grease and wine stains. It is also used in the Textile industry during scouring, bleaching, and dyeing. Its usage also involves Pulp & Paper Industry for controlling the pH in the pulping process, neutralizing the effluent streams, and processing waste paper
