By distilling H2SO4 and NaNO3, i produce my own nitric acid but after the distillation, the stuff who remains in the boiling flask is hard like rock and is very difficult to eliminate...
anyone has a tip for cleaning this shit ?
thanx

Put some hot vinegar (5% acetic acid) in and let it sit over night. In the morning if its not all dissolved youll be able to break it up and pour it out.

It may but i wouldnt bother, as concentrating it may take longer than using the 5% stuff to clean it =). To concentrate acetic acid you must first convert it to sodium acetate and distill it with sulfuric acid. More info is on mega's page.
