Sodium Sulfate
Sodium Sulfate. Sodium sulfate is an important compound of sodium. When anhydrous, it is a white crystalline solid of formula Na 2 SO 4. The decahydrate, Na 2 SO 4 10H 2 O, is known as Glauber's salt. Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping, though it has many other uses.

Why sodium sulphate has water absorbing capability?
Sodium sulphate reacts readily with water at room temperature to form hydrates up to sodium sulphate decahydrate, $ce{NaSO4cdot10H2O}$. $$ce{NaSO4 + 10H2O -> NaSO4cdot10H2O}$$ This means that $ce{NaSO4}$ can absorb up to 10 mol of water for every 1 mol of salt that is used, making it one of the most effective drying …
Solved How does the drying agent, anhydrous sodium sulfate…
Chemistry questions and answers. How does the drying agent, anhydrous sodium sulfate, remove water from the organic extract?
