English
[edit]
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]Noun
[edit]aqua regia (uncountable) (abbreviation A.R.)
- (inorganic chemistry, archaic) A mixture of three parts concentrated hydrochloric acid to one part concentrated nitric acid, named for its ability to dissolve gold.
- Synonyms: aqua regis, nitro-hydrochloric acid
- 2005, D.J. Krus, Elements of Propositional Calculus[1]:
- 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.
