Sulfate 250 mg/L SMCL Sulfates of calcium and magnesium form hard sc ale. Large concentrations of sulfate have a laxative effect on some people and, in combination with other ions, give water a bitter taste. Chloride 250 mg/L SMCL Large concentrations increase the corrosiveness of water and, in combination with sodium, give water a salty taste.

Although well known as table salt, sodium chloride's major uses include highway deicing, chemical feedstock and food processing. Sodium nitrate is a type of saltpeter, which is most well-known for its use in the production of gunpowder. Sodium sulfate is another common sodium salt, which has many uses. It is used in glass …

The sodium ion is the principal cation in water from igneous terrane. When brought into solution, sodium tends to remain in that state and is not active in precipitation reactions. Sodium is retained in the uncombined state by adsorbing to mineral surfaces, especially minerals with high cation- exchange capacities such as clays (Hem, 1970).
Sodium sulfate is used in the glass-making industry to remove air bubbles; in textiles to allow for even absorbtion of dyes; and as filler in detergents and wood pulp paper. A fairly new use for salts such sodium sulfate and sodium nitrate is as thermal energy storage, since they can absorb quite a bit of heat and then slowly release it ...
Thenardite is a sodium sulfate salt (Na 2 SO 4) usually found together with other sulfate salts such as mirabilite or Glauber's salt (Na 2 SO 4 ·10H 2 O), glauberite (Na 2 Ca(SO 4) 2), bloedite or astrakanite (Na 2 Mg(SO 4) 2 ·4H 2 O), or burkeite (Na 6 (CO 3)(SO 4) 2).. Sodium sulfate deposits can be classified into three main groups: …
The Souris River Basin is an international basin in southeast Saskatchewan, north-central North Dakota, and southwest Manitoba. Sustained exceedances of water-quality objectives for total phosphorus, sodium, sulfate, total dissolved solids, and total iron have been reported since the late 1990s at the two binational sites on the Souris River …

13.9 million tons (15.3 million short tons). Borax, salt, and sodium sulfate were produced as coproducts of sodium carbonate production in California. Chemical caustic soda, sodium bicarbonate, and sodium sulfite were manufactured as coproducts at several of the Wyoming soda ash plants. Sodium bicarbonate was produced at an

By 1990, the U.S. sodium sulfate industry had excess capacity to supply a declining domestic market. Several companies that recovered sodium sulfate considered modifying their technology to produce nonsodium sulfate byproducts that may have more market potential. U.S. sodium sulfate exports have increased to supply material to foreign …
Sodium sulfate is defined as the sodium salt of sulfuric acid. The sodium sulphate chemical formula is Na 2 SO 4.. Anhydrous sulfate can be described as a white crystalline solid, which is also called mineral thenardite, whereas, the decahydrate Na 2 SO 4.10H 2 O has been called either mirabilis or Glauber's salt.. When Na 2 SO 4.7H 2 O is …
This Hydrologic Atlas shows concentrations of calcium, sodium (or sodium plus potassium), sulfate, and chloride in stream water of 11 of the Western States, regardless of the sources from which the mineral constituents came. The maps are, in a sense, a historical summary, showing concentrations observed to 1956 and reported in published …
