Precipitated Gold facts

While investigating facts about Precipitate Gold Corp and Precipitate Gold Stock Price, I found out little known, but curios details like:

George de Hevesy dissolved the Nobel Prizes of James Franck (1925) and Max von Laue (1925) in acid to prevent the Nazis from confiscating them in 1940. After the war, he precipitated the gold and The Nobel Society recast the medals with the original material, presenting them to Franck and Laue.

how to precipitate gold from aqua regia?

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.

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across. Here are 8 of the best facts about Precipitate Gold From Chloroauric Acid and Precipitate Gold Stock I managed to collect.
