Question

sodium sulphrate is also known as_salt​

Answer 1

Anhydrous sulfate is a white crystalline solid also known as the mineral thenardite, while the decahydrate Na2SO4.10H2O has been known as Glauber’s salt or mirabilis.

Na2SO4.7H2O is transformed to mirabilite when it is cooled. Mirabilite is the natural mineral form of the decahydrate. About two-thirds of the world’s production of sodium sulfate is obtained from mirabilite. It is also produced from by-products of chemical processes such as hydrochloric acid production.

In 1625, Johann Rudolf Glauber discovered the sodium sulfate from Austrian spring water, there so the hydrate form is known as Glauber’s salt. Due to its medicinal properties, he named it sal mirabilis
