Etymology[edit]

Borrowed from Latin aqua regia (literally royal water), so named because it is one of the few solvents capable of dissolving noble metals.

Pronunciation[edit]

  • IPA(key): /ˈɑː.kwə ˈɹeɪ.ɡi.ə/, /ˌækwə ˈɹiːdʒi.ə/, enPR: ăʹkwə-rēʹjē-ə
  • (file)

Noun[edit]

aqua regia (uncountable) (abbreviation A.R.)

  1. (inorganic chemistry, archaic) A mixture of three parts concentrated hydrochloric acid to one part concentrated nitric acid.
    • 2005, D.J. Krus, Elements of Propositional Calculus
      Consider another example. 'If gold is placed in aqua regia then it dissolves.' Aqua regia is a mixture of nitric and hydrochloric acids that dissolves gold or platinum. Observation of gold dissolving in aqua regia (argument 1 1) lends credence to the above conditional statement.
      Not placing the gold into aqua regia and gold not dissolving (argument 0 0) does not disprove the truth-value of this conditional.
    Synonyms: aqua regis, nitro-hydrochloric acid
