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.

2 c 3 a + c 3 a·3cŜ·h 32 → 3 c 3 a·3cŜ·h 12 tricalcium aluminate + ettringite → mono-sulfate aluminates (AFm) When it reacts with concrete, it causes the slab to expand, lifting, distorting and cracking as well as exerting a pressure onto the surrounding walls which can cause movements significantly weakening the structure.
Sodium fluorosilicate is a compound with the chemical formula Na 2 [SiF 6]. Unlike other sodium salts, it has a low solubility in water. Unlike other sodium salts, it has a low solubility in water. Natural occurrence
In solution the fluorosulfate anion is completely ionised. The volume of the ions is 47.8 cm 3 /mol. [3] Most metal ions, and quaternary ammonium ions, can form fluorosulfate salts. [3] Different ways to make these salts include treating a metal chloride with anhydrous fluorosulfuric acid, which releases hydrogen chloride gas.
Trisodium phosphate (TSP) is an inorganic compound with the chemical formula Na 3 P O 4. It is a white, granular or crystalline solid, highly soluble in water, producing an alkaline solution. TSP is used as a cleaning agent , builder , lubricant , food additive , stain remover , and degreaser .
Mirabilite, also known as Glauber's salt, is a hydrous sodium sulfate mineral with the chemical formula Na 2 SO 4 ·10H 2 O. It is a vitreous, colorless to white monoclinic mineral that forms as an evaporite from sodium sulfate-bearing brines. It is found around saline springs and along saline playa lakes.
Sodium metatungstate is the inorganic compound with the formula Na 6 [H 2 W 12 O 40], sometimes written 3Na 2 WO 4 ·9WO 3 ·H 2 O. It is also referred to as sodium polytungstate (SPT). This salt has been used in the manufacture of dense aqueous solutions .
