The compound with the formula FeCl3 is called iron(III) chloride.
Iron(III) chloride is classified as an ionic compound. This is because it is formed from the transfer of electrons between a metal and a non-metal. In FeCl3, iron (Fe) donates three electrons to chlorine (Cl) atoms. This results in the formation of iron cations (Fe3+) and chloride anions (Cl–). The electrostatic attraction between the positively charged cations and negatively charged anions holds the compound together, characteristic of ionic bonds. The high melting and boiling points further support its ionic nature.
