Sodium sulfate anhydrous, also known as sodium sulfate crystals and thenardite, is a white crystalline solid with the chemical formula Na2SO4. It consists of two sodium ions (Na+) and one sulfate ion (SO42-). Sodium sulfate is a vital compound that serves a number of important industrial applications. It is widely used as a drying agent because it has a strong affinity for water molecules and can effectively remove them from other substances. It is also a common ingredient in a variety of glass and paper products, textiles and dyes, and cleaning products. Additionally, it can be used as a buffering agent and stabilizer. Sodium sulfate anhydrous can be found naturally in saline lakes, such as the Great Salt Lake in Utah, and as a byproduct of many chemical industrial production processes.

Generally, sodium sulfate anhydrous is considered safe when it is consumed in appropriate amounts. However, it can be toxic when ingested in excessive amounts. Symptoms of an overdose include dehydration, electrolyte imbalance, and gastrointestinal distress. It can also interact with certain medications and cause side effects.

The most common method for detecting sodium sulfate anhydrous in water is through flame photometry. A sample of water is collected in a container and an aliquot of it is then atomized in a flame photometer. The emission intensity at 589 nm is then measured, and the concentration of the anhydrous sodium sulfate in the sample is determined using a calibration curve.
