Aqua Regia facts

While investigating facts about Aqua Regia Preparation and Aqua Regia Is A Mixture Of, I found out little known, but curios details like:

Hungarian chemist Georgy de Hevesy dissolved Max von Laue and James Franck's Nobel Prize medals in a highly corrosive mix of acids, aqua regia, to hide from the Nazis. After the war, he precipitated the gold out of solution and sent it to Stockholm where the medals were recast.

how aqua regia dissolve gold?

During WWII, George de Hevesy used aqua regia to dissolve the Nobel Prizes of German physicists Max von Laue and James Franck to prevent them being confiscated. He left the solution in his lab, where it was ignored. After the war, he precipitated the gold out and the medals were recast.

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what is aqua regia how does it dissolve gold. Here are 11 of the best facts about Aqua Regia Formula and Aqua Regia Recipe I managed to collect.
