Sodium sulfate
Since sodium sulfate is a compound, people need to know safety facts about sodium sulfate. People have to put sodium sulfate in a closed container. They also have to separate it from incompatible substances. Examples are strong acids, magnesium and aluminum. Sodium sulfate is not expected to be a health hazard when people touch with their skins. It can have a mild toxicity because of ingestion ...
Comparison of Magnesium Sulfate and Sodium Sulfate for ...
· Drying agents, such as sodium sulfate or magnesium sulfate, are used to remove the water from the organic extracts. In the present study, we used nuclear magnetic resonance spectroscopy to study the composition of the phases resulting from salting out and to compare the effectiveness of sodium sulfate and magnesium sulfate as drying agents. The study showed that considerable .
