CAS 7757-82-6

Sodium sulfate

Description:

Sodium sulfate, with the CAS number 7757-82-6, is an inorganic compound composed of sodium and sulfate ions. It typically appears as a white crystalline solid and is highly soluble in water, making it useful in various applications. Sodium sulfate is hygroscopic, meaning it can absorb moisture from the environment, which can affect its physical properties. It has a high melting point and is stable under normal conditions, but it can decompose at elevated temperatures. This compound is commonly used in the manufacture of detergents, glass, and textiles, as well as in the paper industry. Additionally, it serves as a drying agent in organic synthesis and is utilized in laboratory settings for various chemical reactions. Sodium sulfate exists in several hydrated forms, with the decahydrate (Na2SO4·10H2O) being the most common. Its non-toxic nature and relatively low cost make it a favorable choice in many industrial processes. However, care should be taken to handle it properly, as large quantities can lead to environmental concerns if released into water systems.
