Etymologies

from The American Heritage® Dictionary of the English Language, 4th Edition

[hydr(o)– + (amm)onium.]

Examples

  • For chemists, the term hydronium ion (H3O+) is often substituted for hydrogen ion to reflect the association of a hydrogen ion with a molecule of water.

    PH

  • One might wonder whether an up quark, an uranium nucleus, a hydronium ion, a charged water droplet, and a balloon that has been rubbed on someone's jumper all belong to one kind.

    Natural Kinds

  • Goldman said he was certain glycine would be formed within the first microsecond through a spontaneous reaction of the glycine/CO2 complex with a hydronium ion to form glycine, water and carbon dioxide, but the simulation is too complex to run long enough to see this.
