Hi guys,

I need urgent advice ! I have been asigned a presentation for chemistry class and I need your help. I've got everything done probably quite OK, BUT i need equiations for production of magneisum and seperately equations for preperation. I hope you understand. I searched all the net, but I couldn't find exactly what I needed. I donno if i said it correctly in english - so I'll further explain. The equations for preparation should be how you can seperate Mg in a let's say school laboratory (small scale). The equations for production should be for the huge, indusrtial scale production of seperated Mg. I hope you'll understand me, because it's pretty vital for me. Thanks in advance

All over the web and couldn't find industrial preparations of magnesium?

Thanks for the reply. Well not exactly. That one I found, but I need the ones for preparation - and all I can find is the industrial, that's why I said I need them seperately. So I need the preparation in small scale. Thanks

One method is to do a small scale electrolysis. You can use one of the halide salts such as MgCl2 (714 °C)
You would need a crucible. A steel pot will work also.
Use a iron cathode and graphite anode.

Or you can use a more reactive metal than Mg such as Na. Heat MgCl2 with the metallic Na and it will reduce the Mg ions.
