aqua regia from HCL and sulfuric acid?

i have 4 l of spring water, 200 ml clear concentrated HCL (muriatic acid), and 20-100 ml clear concentrated sulfuric acid (H2S04). is there a way to turn the sulfuric acid to nitric acid so i have aqua regia?

the sulphuric acid needs to be VERY concentrated . it should move like oil .... if it looks and moves around like water it's too dilute ...battery acid is too dilute ......

put some on a sugar cube and 98% concentrated sulphuric acid will turn it into charcoal ... see Youtube

If you can get come of this 98% sulphuric acid it will react with potassium or sodium nitrate , heat the mixture and nitric acid will boil off and can be collected in a cooled container .

Nope. You need a nitrate salt. As the poster above me mentioned. Do you have a way to do distillations? If you do, then you can make you’re HNO3 and mix with you’re HCl to get the desired product.

Does this forum not support BBC code?
