Ferrous - Physico-chemical Properties
| Physical and Chemical Properties | Physical and chemical properties ferrous iron, also known as ferrous sulfate or green alum, is blue-green monoclinic crystals or particles without smell. Ferrous sulfate crystals are columnar or granular aggregates, which are irregular blocks. Molecular weight is 278.05 ,pH value is 3, melting point is 64 degrees Celsius, strong thermal decomposition, soluble in water, glycerin, insoluble in ethanol. It can be used for making iron salts, iron oxide pigments, mordants, water purifiers, preservatives, disinfectants, etc. It is used as an anti-anemia drug in medicine. |
Ferrous - Introduction
Ferrous(Ferrous) refers to the 2 oxidation state of iron, with the chemical formula Fe²². The following is a description of the nature, use, preparation and safety information of the Ferrous:
Nature:
1. Ferrous is a metal with iron gray color, which has high electrical conductivity and thermal conductivity.
2. it is easily oxidized in the air, the formation of iron oxide and corrosion, so often need to keep in a dry environment.
3. Ferrous can be dissolved in water, and can react with some acid to form the corresponding salt.
Use:
1. Ferrous salt is a common pigment, commonly used in paints and dyes.
2. Ferrous is used as fertilizer in agriculture to supplement the iron in the soil.
3. In addition, Ferrous salts are also used in the preparation of drugs and water treatment agents.
Preparation Method:
1. Ferrous can be obtained by reducing iron ions, such as adding sulfite or hydrogen.
2. Ferrous can also be prepared by electrolysis of iron-containing solution.
Safety Information:
1. Ferrous salt is irritating. When handling Ferrous salts, wear appropriate protective gloves and glasses to avoid skin and eye contact.
2. Ferrous salt intake and inhalation may be harmful to the human body, it should not be ingested or inhaled.
