Hg metal from HgO?
i was thinking of something like a 500ml distillation flask, with about 200grams of HgO in it, hooked to a 500mm liebig. heat the flask with a torch and mercury drops out of condensor. Right?
Answer:
I agree with drofchem - generating mercury in this fashion is a very dangerous and foolish idea - please do not even attempt it.
It you are thinking of doing it, DO NOT vent the fumes to the outdoors. All the fumes MUST be vented into a certified fume hood, and I really don't think that is good enough! Above all, make sure that the reaction flask has a small positive pressure of nitrogen flowing through it and that it is air tight (except for the exhaust gases). The entire apparatus should be set up in a the same hood as the fumes are vented into.
First, be cautious about mercury vapor.
Mount a condenser on top of a boiling flask and allow the mercury to reflux. When all the oxygen has been driven away, and the apparatus is cool, collect your mercury from the flask.
To ensure it all condenses, plumb a hose from the top of the condenser to one of two holes in a flask immersed in ice water. The other hole will vent the oxygen to the hood or otherwise outdoors.
If I were you I would not heat anything containing Mercury that is unless you want to die
All you would have to do is obtain red mercuric oxide, place it in a dish and heat it to drive off the oxygen. It is a simple decomposition reaction. It is very simple and there is no need for a complex distillation system. Be very cautious with mercury vapor, be sure to perform it in a hood.
