Sodium sulfate anhydrous(na2so4) called Glauber Salt or sulfate of soda. It is chemically very stable and has an appearance of white crystalline solid. It has unsteady reaction towards most reducing or oxidizing agents at normal temperatures.
Sodium sulfate anhydrous is an electrolyte replenisher and is used in isosmotic solutions so that administration does not disturb normal electrolyte balance and does not lead to absorption or excretion of water and ions. Sodium sulfate is an inorganic sodium salt.
