it's called aquaregia (maybe I mistyped, because I forget how to type it)
gold can be dissolved in this solution. In my hometown we called it "king of acid water" as slang word

actually, HNO3 plus H2SO4 is known as nitrating mixture. its job is to introduce nitro group(NO2) on an aromatic ring. whenever this mixture is with benzene,nitro group immediately gets attached to the ring.
actually the nitrating mixture produces NO2+ electrophile, which attacks the ring and gets substituted.hence the mechanism is electrophilic substitution. hope this helps :)

in organic chemistry is used as reactant to ad a nitro group in a phenyl ring
"Aquaregia" is 2:1 parts of HCl (37%) and HNO3 (fuming).

On addition of aq.HNO3 plus H2SO4, it gives a some kind of catalyst which is used in the reaction of ester & alcohol to form carboxylic acid.

when we mix these two acids in 2:1 proportion we will get a new type of solution called "aqua regia" which is a very good solvent for noble metals like gold, platinum,etc. which we cannot dissolve in normal solvants

A lot of heat is release and the mixture assumes a brown colour and is highly oxidizing.
