Ferrous sulfate Magnesium carbonate

Substances (hat are ordinarily efflorescent are sodium sulfate decahy-drate. sodium carbonate decahydrate. magnesium sulfate hcpiahydrate. and ferrous sulfate hepiahydrale. When the saturated solution of a substance in water has a water vapor pressure greater than that of the surrounding atmosphere, evaporation of the water from solution takes place. 

Salts Compounds formed by the union of acids and bases, by the action of alkalies upon metals, or by the direct union of elements. The term is often incorporated in the common name of salts used as pharmaceuticals bitter salts, epsom salt, or Seidlitz salt (magnesium sulfate), preparing salt (sodium stannate), Preston s salts (ammonium chloride), Rochelle salt or Seignette s salt (potassium and ammonium tartrate), salt of Mars (ferrous sulfate), salt of Saturn (lead acetate), salt of tartar (potassium carbonate), salt of tin (stannous chloride), salt of wisdom (mercury bichloride and ammonium chloride), sore-throat salt (fused potassium nitrate), vinegar salts (calcium acetate), and vomiting salt (zinc sulfate). The term is also applied to some acids, such as salt of lemon or sour salt (citric acid), salt of sorrel (oxalic acid), and spirit of salt (muriatic acid). ... 

The sodium carbonate formed from the removal of temporary hardness is available to precipitate any calcium or magnesium salts present as permanent hardness. Thus, the usual water treatment for removal of hardness involves adding a mixture of quicklime (CaO) and sodium carbonate in accordance with the amount of permanent hardness present. Sometimes a coagulant such as alum (Al2(S04)3 I4H2O) or ferrous sulfate will be added to help coagulate and settle any finely divided hardness in suspension [18]. 

Uneertain. One suggestion is that magnesium sulfate changes ferrous sulfate into less easily absorbed salts, or increases its polymerisation. Carbonates possibly cause the formation of poorly soluble iron complexes. Aluminium hydroxide is believed to precipitate iron as the hydroxide and ferrie ions can become intercalated into the aluminium hydroxide crystal lattice, leaving less available for absorption. 

Commonly used coagulants are inorganic (Bratby, 2006 Anon, 2014) and are based on aluminum (i.e., aluminum sulfate, aluminum chloride, sodium aluminates), iron (i.e., ferric sulfate, ferrous sulfate, ferric chloride, ferric chloride sulfate), hydrated lime, or magnesium carbonate. They are often the cheapest, most widely available, and effective coagulants.

The medium for the production of variotin, contained 3.0% sucrose, 0.2% dipotassium phosphate, 0.05% potassium chloride, 0.05% magnesium sulfate (hydrated), 0.001 % ferrous sulfate (hydrated), and 0.3 % sodium nitrate. Inorganic nitrogen sources were found to be more suitable for variotin production than organic nitrogen sources. Ammonium nitrate or ammonium sulfate could also be used. Of 11 sugars tested, sucrose was the most suitable carbon source for variotin formation (Takeuchi et al., 1959). The production of variotin reached a maximum by 4 or 5 days at 25 in shaken culture, or by 90 hours at 25 by aerated tank fermentation. 

A medium (containing corn steep liquor calcium carbonate sucrose ammonium, ferrous, manganese, and zinc sulfates and ammonium, cobalt, and magnesium chlorides) is sterilized and diluted with water to the desired concentration. It is inoculated with Streptomyces aureofaciens, kept at 27°C, and aerated and agitated for 60 hours, with lard oil added to control foaming (66). 

And finally, appendices provide a user s guide for the FREZCHEM model and tables of model parameters. Version 9.2 of this model includes the precipitation-dissolution of chloride, nitrate, sulfate, and bicarbonate-carbonate salts of calcium, magnesium, sodium, potassium, and ferrous iron. This version also contains strong acid chemistries (hydrochloric, nitric, and sulfuric), gas hydrate chemistries (carbon dioxide and methane), and tem-perature/pressure dependencies. Electronic copies of the FORTRAN code are available from the senior author (giles.marion dri.edu). 

FERROUS AMMONIUM SULFATE (10045-89-3) Reacts violently with reducing agents, acrolein, alcohols, chlorine trifluoride, ethers, fluorine, hydrazine, hydrazinium perchlorate, hydrogen peroxide, finely divided aluminum or magnesium, ammonium perchlorate, mercury(II) dinitrate, peroxyfuroic acid, sodium acetylide, tetranitromethane. Sensitizes most organic azides that are unstable shock and heatexplosives. Forms explosive materials with l,3-di(5-tetrazoyl)triazene. Incompatible with glycidol, isopropyl chloro-carbonate, nitrosyl perchlorate, sodium borohydride. 

III. Chalybeate waters which contain salts of iron in greater ]iroportion than 4 parts in 100,000. They contain ferrous bicarbonate, sulfate, crenate, and apocrenate, calcium carbonate, sulfates of potassium, sodium, calcium, magnesium, and aluminium, notable quantities of sodium chlorid, and frequently small amounts of arsenic. They have the taste of iron and are usually clear as they emerge from the earth. Those containing ferrous bicarbonate deposit a sediment on standing, by loss of carbon dioxid, and formation of ferrous carbonate.
