Product Description
What Is Sodium Sulfate?
Sodium Sulfate (Na2SO4) is a white, odorless crystalline compound used in industries such as detergents, glassmaking, and as a drying agent. It occurs in anhydrous (thenardite) and hydrated (mirabilite) forms.
Preparation:
- Reaction with Sodium Carbonate: Sodium sulfate is produced by reacting sulfuric acid (H2SO4) with sodium carbonate (Na2CO3).
- Byproduct in Hydrochloric Acid Production: It can also be obtained as a byproduct when producing hydrochloric acid from sodium chloride.
Hydration occurs when water is added to anhydrous sodium sulfate, resulting in the formation of hydrated sodium sulfate.

User Asked Question:
Q: How does anhydrous sodium sulfate differ from its hydrated counterpart?
A: The key difference between anhydrous and hydrated sodium sulfate is that anhydrous sodium sulfate is a dry powder without any water content, whereas hydrated sodium sulfate, also known as mirabilite, includes water molecules and is typically found in a crystalline form.
