Ferrous sulfate FeSO

Ferrous sulfate (FeSO ) is also known as iron sulfate or iron vitriol. It is used in the production of various chemicals, such as sulfur dioxide and sulfuric acid. 

DISSOLVE A SMALL CRYSTAL OF IRON SULFATE (FERROUS SULFATE, FeSO ) IN HALF A TEST TUBE FULL OF WATER. 

Ferrous sulfate, FeSO H, 0, is made by dissolving iron in sulfuric acid, or by allowing pyrite to oxidize in air. The green crystals of the substance are efflorescent, and often have a brown coating of a basic... 

FERROUS SULFATE. FeSO. TH O. Alloy 3003 was resistant to solid ferrous sulfate while 5154 alloy suffered mild attack ( 4 mpy) in laboratory tests under conditions of 100% relative humidity at ambient temperature. In other laboratory tests at ambient temperature, aqueous solutions (0.0001-10%) caused mild attack ( -3 mpy) of 1100 alloy. Aluminum spray tanks and alloy AJ56.0 valves have been used with ferrous sulfate solutions. At elevated temperature, ferrous sulfate oxidizes to ferric sulfate which is aggressive to aluminum alloys.

ADD HYDROGEN PEROXIDE SOLUTION. LIGHT-GREEN FERROUS SULFATE SOLUTION TURNS REDDISH-BROWN. H,Oj HAS OXIDIZED FeSO TO FERRIC SULFATE (FeJSO, ,). 

Preparation of Wood-Methyl Methacrylate Graft Copolymer. Wood Meal (0.5 g), an acetic acid-sodium acetate buffer solution with pH 4.6 (5 ml), a ferrous sulfate aqueous solution (5 ml FeSO 1x10 mole), MMA (8 ml), and a hydrogene peroxide aqueous solution ( 5 ml HO. 1x10 mole) were mixed in this order. After degassed, the flask was sealed and shaken at 50 °C for 1 to 8 h. The reaction mixture was poured into a large excess of methanol. To remove homo polymer, the product was then extracted with acetone for 36 - 72 h. 

Ferrous sulfate (feosol, others) is the hydrated salt, FeSO 7Hff), which contains 20% iron. Ferrous fumarate (feostat, others) contains 33% iron and is moderately soluble in water, stable, and almost tasteless. Ferrous gluconate (fergon, others), which contains 12% iron, also is used in the therapy of iron-deficiency anemia. Polysaccharide—iron complex (niferex, others), a compound of ferrihydrite and carbohydrate, has comparable absorption. The effective dose of these preparations is based on iron content. 

Ferric Sulfates are quite numerous, and are formed by oxidations of ferrous sulfate under different conditions. The normal sulfate, (Fea)(SO0>, is formed by treating solution of FeSO< with HXOa, and evaporating, after addition of one molecule of HaSOi for each two molecules of FeSOi. The Xiq. fer. tersulfatis (XT.S.) contains this salt. It is a yellowish-white, amorphous solid. 

Goethite process. Precipitation of goethite, FeOOH, is performed by adding a solution of ferrous sulfate to zinc calcine along with oxygen or air to ensure the oxidation of ferrous iron at a pH of about 3. Ferrous sulfate comes from copperas (FeSO 7H2O) or from the leaching of zinc ore concentrates ... 

I The color of hydrangea blossoms depends on the pH of the soil in which they are grown. Acidic soil (created by the application of ferrous sulfate, or FeSO ) creates blue blossoms. Alkaline soil (created by the application of lime) creates pink blossoms. 

Salts of Iron.—Sulfates.—Ferrous SviXtAte—Protosulfate—Green vitriol—Copperas—Ferri sulfas (TJ. S. Br.)—FeSO,- - Aq—151.9 -I- 126—is formed (1) by oxidation of the snlild, FesS , formed in the manufacture of HaSO (2) by dissolving Fe in dilute HaS04.
