- Na2SO4 as well as several related hydrates.
- solubility in water
- anhydrous: 4.76 g/100 mL (0 °C), 13.9 g/100 mL (20 °C)[1]
- 42.7 g/100 mL (100 °C) heptahydrate:, 19.5 g/100 mL (0 °C), 44 g/100 mL (20 °C)
- "Although sodium sulfate is generally regarded as non-toxic,[28] it should be handled with care. The dust can cause temporary asthma or eye irritation; this risk can be prevented by using eye protection and a paper mask. "
- The decahydrate of sodium sulfate is known as Glauber's Salt. It melts at around 90F .
- 2NaHCO3 + MgSO4 → Na2SO4 + Mg(OH)2 + 2CO2
- do not confuse with sodium sulfide. The sulfide is very caustic.
