Reactions
Erbium metal tarnishes slowly in air. Erbium burns readily to form erbium (III) oxide:
Formation of erbium oxide: 4 Er + 3 O2 → 2 Er2O3 Erbium oxide is insoluble in water and soluble in mineral acids. Er2O3 readily absorb moisture and carbon dioxide from the atmosphere. It can react with acids to form the corresponding erbium(III) salts.
Reaction with hydrochloric acid: Er2O3 + 6 HCl → 2 ErCl3 + 3 H2O

Famous quotes containing the word reactions:
“Separation anxiety is normal part of development, but individual reactions are partly explained by experience, that is, by how frequently children have been left in the care of others.... A mother who is never apart from her young child may be saying to him or her subliminally: “You are only safe when I’m with you.””
—Cathy Rindner Tempelsman (20th century)
“In this Journal, my pen is a delicate needle point, tracing out a graph of temperament so as to show its daily fluctuations: grave and gay, up and down, lamentation and revelry, self-love and self-disgust. You get here all my thoughts and opinions, always irresponsible and often contradictory or mutually exclusive, all my moods and vapours, all the varying reactions to environment of this jelly which is I.”
—W.N.P. Barbellion (1889–1919)
“We have all had the experience of finding that our reactions and perhaps even our deeds have denied beliefs we thought were ours.”
—James Baldwin (1924–1987)
