Sodium Sulfate Anhydrous Decahydrate
CAS Number: 7757-82-6 Sodium Sulfate Anhydrous and 7727-73-3 Sodium Sulfate Decahydrate
Molecular Formula: Na2SO4
Molecular Weight: 142.04
Sodium Sulfate Anhydrous Decahydrate
Sodium Sulfate USP Grade Specifications
Na2SO4-10H2O -- 322.20
Sulfuric acid disodium salt, decahydrate.
Disodium sulfate decahydrate CAS 7727-73-3
Anhydrous 142.04 CAS 7757-82-6
Sodium Sulfate contains ten molecules of water of hydration, or is anhydrous. It contains not less than 99.0 percent of Na2SO4, calculated on the dried basis.
Identification: A solution (1 in 20) responds to the tests for Sodium 191 and for Sulfate.
Acidity or alkalinity: To 10 mL of a solution, containing the equivalent of 1.0 g of Na2SO4-10H2O in 20 mL of water, add 1 drop of bromothymol blue TS: not more than 0.50 mL of either 0.010 N hydrochloric acid or 0.010 N sodium hydroxide is required to change the color of the solution.
Loss on drying: Dry at 105 for 4 hours: the decahydrate loses between 51.0% and 57.0% of its weight, and the anhydrous form loses not more than 0.5% of its weight.
Chloride: A portion equivalent to 1.0 g of Na2SO4·10H2O ( Sodium Sulfate Decahydrate )shows no more chloride than corresponds to 0.30 mL of 0.020 N hydrochloric acid (0.02%).
