UC Posted April 20, 2009 Share Posted April 20, 2009 2Mg + 2NaOH -> 2MgO + 2Na + H2 Aqueous solution of NaOH or something else? not at all, especially in aqueous solution. look up reactivity series. I dont think sodium can be distilled out of the mix of molten NaOH and Mg too easily or you could cheat with Le Chatlier's principle and a lot of heat.

Theophrastus Posted April 21, 2009 Share Posted April 21, 2009 Agreed, all it does, is induce the corrosion of the magnesium metal, and release hydrogen gas, in the process. Link to comment Share on other sites More sharing options...

Actually, I think the corrosion of the magnesium would be hindered by formation of a hydroxide skin. Unlike aluminum hydroxide/oxide, which you are probably thinking of, magnesium hydroxide is not amphoteric. Link to comment Share on other sites More sharing options...
hermanntrude Posted April 22, 2009 Share Posted April 22, 2009 Oh god, not another "I think I know how to make sodium" thread. I'd like to make and sticky a thread called "you cant make sodium" 1 Link to comment Share on other sites More sharing options...
