It's name is aqua regia and it has been known since the Middle Ages. Aqua regia is Latin for 'royal water' because it can dissolve royal metals, such as gold and platinum, which amazed the alchemists at the time.
Aqua regia is made by combining one part concentrated nitric acid (HNO3 ) to three parts concentrated hydrochloric acid ( HCl ). It must be made fresh because it will decompose quickly, therefore it cannot be ordered.
