Metathesis reaction: BaCl2+Na2SO4=BaSO4↓+2NaCl;
Stability: stable, insoluble in strong acid, aluminum, magnesium, moisture absorption. When exposed to the air, it will easily absorb moisture and become water-containing sodium sulfate. It transforms into hexagonal crystal at 241℃. The high-purity, fine-grained anhydrous substance is called sodium sulfate. Easily soluble in water. It feels cool. The taste is refreshing and salty. It is easily hydrated in moist air, and turns into powdery water-containing sodium sulfate to cover the surface. Anhydrous Glauber's salt is produced in salt lakes containing sodium sulfate brine, and symbiosis with Glauber's salt, glauber's salt, diarrhea salt, magnesite, gypsum, glauber's salt, rock salt, soaking alkali, etc.; it can also be formed by dehydration of Glauber's salt; volcanoes; There is a small amount of output around the fumarole.

Toxicity: non-toxic
Toxicological data: mouse oral: LD50 5989mg/kg
Ecological data: It is slightly harmful to water. If there is no government permission, do not discharge the material into the surrounding environment. [2]
In addition, Na2SO4 can also be dissolved in water as an electrolyte.
