If I distill aquaregia (HNO3 + 3HCl) with water in the receiving flask of a closed system will I get HCl or nitrous gas going over the head. Also if
I add water to the aqua Regia first will that stop the HCl distilling before the boiling point for HNO3 is reached?
Because of the potential fumes which could linger in the distillation system I thought I would ask before going ahead and finding out experimentally.

You can't 'distil' AR. Don't try it.

Ok blogfast. You have my curiosity piqued. What would happen if one was to try it?

It did seem problematic to distill but it was an obvious thought to try and I was curious.
So if you wanted to separate the two acids how may this be achieved?

Aqua regia is not a stable mixture. It decomposes to reactive species such as nitrosyl chloride and free chlorine gas slowly at room temperature and
probably quite rapidly if heated. I would suspect heating aqua regia is a BAD thing to even try.
