Sodium carbonate Na2CO3 PubChem

IDENTIFICATION: Sodium carbonate is a white crystalline powder or grayish-white lumps. It is also known as washing soda or soda ash. It is odorless and tasteless. It is soluble in water. It occurs worldwide naturally and specifically in the minerals trona and nahcolite. USE: Sodium carbonate is an important commercial chemical.

TRONA (Hydrated Sodium Bicarbonate Carbonate)

Trona is the type mineral so-to-speak for several sodium carbonates that form in non-marine evaporite deposits. Other sodium carbonates include gaylussite, natron, pirssonite, northupite, nahcolite and thermonatrite. Trona is probably the most common and well known of these minerals.

Soda Ash Ciner

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

Soda Ash Statistics and Information

Soda ash is the trade name for sodium carbonate, a chemical refined from the mineral trona or sodium-carbonate-bearing brines (both referred to as "natural soda ash") or manufactured from one of several chemical processes (referred to as "synthetic soda ash"). It is an essential raw material in glass, chemicals, detergents, and other important industrial products.
