In the method provided by the invention, barium sulfate is used to treat the salting-out mother liquor generated in the preparation of sodium hydrosulfite by using the zinc powder method, thus not only can sodium sulfate, barium chloride and powdery barium salt products which have economic values...
(TS-37) was added in small portions and heated on a steam bath for 1H. The precipitate was filtered off and washed with water until free of chloride, dried, burned and weighed. The mass of barium sulfate obtained was multiplied by 0.6086, corresponding to the sodium sulfate (Na2SO3) ...
test solution (TS-37), heat on a steam bath for 1h and filter out the precipitate with further washing with water until being chloride-free. After drying, burn and weigh it with the mass of barium sulphate then multiplying by 0.6086, namely is equivalent to sodium sulfate (of Na2SO3) ...
Sodium Sulfate (Na2SO4) -Sodium sulfate is the sodium salt of sulfuric acid. Anhydrous sodium sulfate is a white crystalline solid also known as the mineral thenardite. While the decahydrate sodium sulfate has been known as Glauber’s salt or mirabilis.
