Soda ash, known chemically as sodium carbonate (Na2CO3), has been in use for thousands of years. Soda ash occurs in many kinds of mineral waters and in mineral deposits of certain springs and lake brines. The richest and most commonly found source of soda ash is trona, a mix of sodium carbonate, sodium bicarbonate, and water. Although trona can be found in many places, the world’s purest, largest, and most accessible deposit is in Wyoming’s Green River Basin.
Unlike the synthetic Solvay and Hou processes, our’s uses an all-natural mining system. Our soda ash is mined from the ground and refined with no additional chemicals. Our supplier’s method is environmentally friendly and produces a pure, high-quality product. Dawn Sci’s all-natural approach keeps costs low, allowing us to distribute all over the world in a cost-effective and competitive manner.

What is Soda Ash?
Soda Ash is the common name for sodium carbonate, which is a chemical compound with the formula Na2CO3. This compound is also known as washing soda and soda crystals. Soda ash can be categorized as an inorganic compound. It can be noted that all hydrates of sodium carbonate are referred to as soda ash. It can also be noted that all these forms of sodium carbonate are white solids under standard conditions. Soda ash is water-soluble and is known to form slightly alkaline solutions when dissolved in water. Traditional methods of obtaining soda ash involved the burning of plants that grow in sodium-rich soils and collecting their ashes (hence the name).
Sodium carbonate is known to be a diazonium salt of carbonic acid (a chemical compound with the formula H2CO3). When dissolved in water, soda ash is known to form carbonic acid and sodium hydroxide. In its pure form, soda ash exists as a white powder and is known to be odorless. It can also be noted that soda ash is a relatively strong base that can act as an antacid.
The preparation of soda ash is generally done using one of four processes – the Leblanc process, the Dual-process, the Solvay process, and the Electrolytic process. Soda ash is a weak acid that is slightly soluble in ethanol and insoluble in alcohol. One of the important applications of this compound is as a water softener.
How is the decahydrate of soda ash formed?
The decahydrate of soda ash is generally formed from water solutions that crystallize in the temperature range of -2.1 to 32.0 degree Celsius.
What kinds of crystal structures are assumed by soda ash?
The two primary crystal structures of soda ash (or sodium carbonate) are monoclinic and orthorhombic.
Are solutions of soda ash acidic or basic?
Aqueous solutions of sodium carbonate are known to be mildly alkaline in nature due to hydrolysis which releases aqueous hydroxide ions.
