- Definition of FeF3
FeF3, also known as Iron(III) fluoride, is an extremely strong chemical compound, consisting of two elements: Iron (Fe) and Fluorine (F). In FeF3, iron has an oxidation number of +3. Its English name is Iron(III) fluoride.
1.2. Atomic structure
FeF3 has one atom of iron and three atoms of fluorine.
1.3. Atomic mass
The molecular structure consists of one atom of iron with a mass of 56 and three atoms of fluorine each with a mass of 19. Therefore, the molecular mass of FeF3 is 56 + 3*19 = 113.
1.4 Ion Structure
FeF3 is an ionic compound, in which the iron(III) ion (Fe3+) and fluoride ion(F-) form a crystal lattice.
- Properties of FeF3
2.1 Physical properties of FeF3
FeF3 is a crystalline solid, with a black or reddish brown colour. It has no characteristic odour. Its pH value is undefined as it is insoluble in water.
2.2 Chemical properties of FeF3
FeF3 is very unstable in humid and hot air, easily transforming into FeF2. It also reacts with strong oxidizing agents.
- Common chemical equations of FeF3
FeF3 does not often participate in chemical reactions, thus there are not as many as five examples of its reaction with metals, acids, non-metals, and salts.
- Preparation of FeF3
FeF3 can be prepared by reacting iron with fluorine at high temperature. The industrial technology for producing FeF3 is not widely disclosed due to its toxicity and strong chemical properties.
