    Europium An application of the complexes of the element (e g , Eu (fod) 3) is as shift reagents in nuclear magnetic resonance This has, however, been banished because of the advent of cheaper superconducting magnets spectroscopy Chiral shift reagents, such as Eu (hfc) 3, are still used to determine enantiomeric purity [57–61] Other applications of Eu in the form of 2+ and 3+ cations, are
  • Europium - an overview | ScienceDirect Topics
    Europium is the most reactive rare-earth element Because of its high reactivity, solid europium rarely looks shiny It reacts with water to form europium hydroxide (Eu (OH)3) It swiftly oxidizes in air, ignites in the range of 150–180°C to form Eu 3+ oxide (Eu 2 O 3) It dissolves in most of the acidic and basic solvents
