Product Details Sodium Carbonate (also known as washing soda, soda ash and soda crystals, and in the monohydrate form as crystal carbonate), Na2CO3, is the water-soluble sodium salt of Carbonic Acid. It is commonly act as a crystalline decahydrate which readily effloresces to form a white powder, the monohydrate. Pure sodium carbonate is a white, odorless powder that is hygroscopic. It has a strongly alkaline taste and forms a moderately basic solution in water. Sodium carbonate is well known for its everyday use as a water softener. 1. Domestic uses ✅ Soda ash is used as a water softener in laundering: It is one of the ingredients of washing powers and other detergents. ✅ Sodium carbonate can be used to remove grease, oil, and wine stains. ✅ Sodium Carbonate is used in some aquarium water pH buffers to maintain a desired pH and carbonate hardnes. ✅ Sodium Carbonate, in a solution with common salt, may be used for cleaning silver 2. Healthcare and Personal Care ✅ Sodium Carbonate is used in toothpastes where it acts as a foaming agent and an abrasive to increase mouth pH temporarily ✅ Sodium Carbonate can be used as a bath salt. 3. Industrial Applications ✅ By far the largest consumption of Sodium Carbonate is in the manufacture of glass, paper, rayon, soaps, and detergents. ✅ Sodium Carbonate is a food additive (E500) used as an acidity regulator, anticaking agent, raising agent, and stabilizer. ✅ Sodium Carbonate is used by the brick industry as a wetting agent to reduce the amount of water needed to extrude the clay. ✅ In casting, it is used as "bonding agent" and is used to allow wet alginate to adhere to gelled alginate. ✅ Sodium Carbonate is used by the cotton industry to neutralize the sulfuric acid needed for acid de-linting of fuzzy cottonseed. ✅ Sodium Carbonate is used as a pH regulator to maintain stable alkaline conditions necessary for the action of the majority of photographic film developing agents. ✅ It is a common additive in municipal pools used to neutralize the corrosive effects of chlorine and raise pH. ✅ In chemistry, it is often used as an electrolyte in the process of electrolysis. ✅ It is also used as a primary standard for acid-base titrations because it is solid and air-stable, making it easy to weigh accurately.
