Salt cake is chemically represented by Na2SO4.

Here's why:
Na2SO4: This is the chemical formula for sodium sulfate, which is commonly known as salt cake.
CaSO4.H2O: This is the chemical formula for gypsum, a hydrated calcium sulfate.
MgSO4: This is the chemical formula for magnesium sulfate, also known as Epsom salt.
BaSO4: This is the chemical formula for barium sulfate, a white, insoluble solid used in various applications.

Salt Cake (Na2SO4) Uses:
Salt cake is used in various industrial processes, including:
Pulp and Paper Industry: It's used in the production of kraft paper.
Glass Industry: It's added to the glass mixture to improve clarity and reduce melting temperature.
Detergent Industry: It's used as a filler in detergents.
Other Applications: It's also used in the production of dyes, textiles, and other chemicals.

Sodium sulfate is the inorganic compound with formula Na2SO4 as well as several related hydrates. All forms are white solids that are highly soluble in water. With an annual production of 6 million tonnes, the decahydrate is a major commodity chemical product. It is mainly used for the manufacture of detergents and in the Kraft process of paper pulping.

Sodium sulfate is also known as Glauber's salt or salt cake. It mainly used for the production of detergent & in Kraft process for the production of pulp.
