| Hazard Information | Back Directory | [General Description]
A yellow crystalline solid or a grayish-white powder. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. FERRIC SULFATE(10028-22-5) is used for water purification, and as a soil conditioner. | [Reactivity Profile]
FERRIC SULFATE is acidic. Corrosive to copper, copper alloys, mild steel, and galvanized steel [USCG, 1999]. | [Air & Water Reactions]
Soluble in water. Hygroscopic in air. Forms acidic aqueous solutions. | [Health Hazard]
Inhalation of dust irritates nose and throat. Ingestion causes irritation of mouth and stomach. Dust irritates eyes and can irritate skin on prolonged contact. | [Potential Exposure]
This material is used in pigments,
textile dyeing, water treatment; and metal pickling. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately. If
this chemical has been inhaled, remove from exposure, begin
rescue breathing (using universal precautions, including
resuscitation mask) if breathing has stopped and CPR if heart
action has stopped. Transfer promptly to a medical facility.
When this chemical has been swallowed, get medical atten tion. Give large quantities of water and induce vomiting. Do
not make an unconscious person vomit. The symptoms of
metal fume fever may be delayed for 4 12 hours following
exposure: it may last less than 36 hours.

The anhydrous salt constitutes grayish-white rhombic crystals; hygroscopic; density 3.10 g/cm3; slightly soluble in cold water; decomposes in hot water. The nonahydrate is a yellow hexagonal crystalline substance; refractive index 1.54; density 2.10 g/cm3; hardness 2.5 Mohs; decomposes at 400°C; very soluble in water. | [Definition]
Ferrous sulfate,also known as ferrisulpas, green copperas, green vitriol, iron sulfate, and melanterite, is composed of blue green monoclinic crystals. It is soluble in water and is used as a mordant for dyeing wool in the textile industry. Ferrous sulfate is also used as a disinfectant and in the manufacture of ink.
| [Preparation]
Iron(III) sulfate may be prepared by oxidation of iron(II) sulfate by hydrogen peroxide, nitric acid or any other suitable oxidizing agent. The reaction is carried out in sulfuric acid. Balanced molecular equations for the reactions with hydrogen peroxide and nitric acid are as follows:
2FeSO4 + H2SO4 + H2O2 → Fe2(SO4)3 + 2H2O
6FeSO4 + 3H2SO4 + 2HNO3 → 3Fe2(SO4)3 + 2NO + 4H2O
Even in the absence of an oxidizing agent, concentrated sulfuric acid alone can1 convert iron(II) sulfate to iron(III) sulfate: 2FeSO4 + 2H2SO4→ Fe2(SO4)3 + SO2 + 2H2O It also may be prepared by treating iron(III) oxide with sulfuric acid:
Fe2O3 + 3H2SO4 → Fe2(SO4)3 + 3H2O

Color Code—Green: General storage may be used.Prior to working with this chemical you should be trainedon its proper handling and storage. Store in tightly closedcontainers in a cool, well-ventilated area away from light,moisture, aluminum, magnesium, copper and its alloys,zinc, galvanized and mild steels. | [Purification Methods]
Dissolve the sulfate in the minimum volume of dilute aqueousH2SO4 and allow it to evaporate at room temperature until yellowish-white crystals start to form. Do not concentrate by boiling off the H2O as basic salts will be formed. Various hydrates are formed; the common ones are the dodeca and nona hydrates which are violet in colour. The anhydrous salt is colourless and is very hygroscopic, but it dissolves in H2O slowly unless ferrous sulfate is added. [Gmelin’s, Iron (8th edn) pp 439-462 1932.] |
| Questions And Answer | Back Directory | [Description]
Ferric sulfate (iron sulfate) is the ferric salt of sulfate. It can be used as a mordant in dyeing and used as a coagulant for the treatment of industrial wastes. In the medical field, it can be used as an astringent and styptic. It is a kind of hemostatic agent being capable of controlling or stopping the flow of blood. It is also recommended that ferric sulfate is a good pulpotomy agent in primary teeth with good potential of substituting the formocresol. It can also be used in pigment, and in pickling baths for aluminum and steel. It is generally prepared through the reaction between ferrous sulfate, sulfuric acid and an oxidizing agent such as nitric acid.
