Sodium sulfate is a typical electrostatically bonded ionic sulfate. The existence of free sulfate ions in solution is indicated by the easy formation of insoluble sulfates when these solutions are treated with Ba 2+ or Pb 2+ salts: Na 2 SO 4 + BaCl 2 → 2 NaCl + BaSO 4. Sodium sulfate is unreactive toward most oxidizing or reducing agents.

Thénardite is an anhydrous sodium sulfate mineral, Na 2 SO 4 which occurs in arid evaporite environments, specifically lakes and playas. It also occurs in dry caves and old mine workings as an efflorescence and as a crusty sublimate deposit around fumaroles. It occurs in volcanic caves on Mount Etna, Italy.
Salt poisoning is an intoxication resulting from the excessive intake of sodium (usually as sodium chloride) either in solid form or in solution (saline water, including brine, brackish water, or seawater). Salt poisoning sufficient to produce severe symptoms is rare, and lethal salt poisoning is possible but even rarer.
Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is an organic compound with the formula CH 3 (CH 2) 11 OSO 3 Na and structure H 3 C−(CH 2) 11 −O−S(=O) 2 −O − Na +. It is an anionic surfactant used in many cleaning and hygiene products. This compound is the sodium salt of the 12 ...
Sulfur water is made out of dissolved minerals that contain sulfate. These include baryte (BaSO 4), epsomite (MgSO 4 7H 2 O) and gypsum (CaSO 4 2H 2 0). [1] It is reported that a notable change in taste to the water is found dependent upon the type of sulfate affecting the water.
For operation, the entire battery must be heated to, or above, the melting point of sulfur at 119 °C. Sodium has a lower melting point, around 98 °C, so a battery that holds molten sulfur holds molten sodium by default. This presents a serious safety concern; sodium can spontaneously ignite in air, and sulfur is highly flammable.
Sulfate attack typically happens to ground floor slabs in contact with soils containing a source of sulfates. [2] Sulfates dissolved by ground moisture migrate into the concrete of the slab where they react with different mineral phases of the hardened cement paste. The attack arises from soils containing SO 2−
