What Is King Acid?
One needs to tell about the value of the gold. This is even called as the King of metals. Gold has got this name not because of its glittering. It is because of lot many features which are not there in the other metals. Air, water, sun, gold can’t show any effect on gold and the general acids can’t do anything to gold. The gold dilutes only in king acid which is made with one part of nitric acid and four parts of hydrochloric acid.
The usage of king acid has happened very interestingly. Niels bohr who belongs to Denmark is a winner of Noble prize. During the time of Second World War, he left Copenhagen unexpectedly due to the attack of Germany. At that time, he has to take the gold medals which belong to him and their employees secretly. He put all those medals in a bottle which contains king acid in order to store them. All those medals were diluted. Later when he came back, he separated the gold and made medals from it.
