SurfSciGuy Posted August 20, 2004 Share Posted August 20, 2004 I wonder if you could use supercritical fluids to provide solvation? Link to comment Share on other sites More sharing options...
Chem-Maniac Posted August 23, 2004 Share Posted August 23, 2004 If Sodium reacts to Sodiumcarbonate, which is quite possible, as you used two electrodes of graphite and put the whole system under a high temperature, it does not react to Sodiumhydroxid in water, and therefore there will be no forming of any hydrogen gas. This is due to the fact that carbonate has a higher charge density than the hydroxide and therefore sticks more to the Sodium which has a high charge density itsself.

budullewraagh Posted August 24, 2004 Share Posted August 24, 2004 i still think that you should do the carbon reduction method Link to comment Share on other sites More sharing options...
idontknow Posted October 18, 2008 Share Posted October 18, 2008 I have tried making sodium by melting down salt and baking soda, and using a car battery charger to do electrolysis. Since baking soda doesn't contain chlorine, that's what I prefer to use. I melt it with a propane torch (the ones used for soldering copper piping), and use steel electrodes to split it. It does make small sodium bubbles, but they burn when they hit air. The end result was a black substance, which would sometimes bubble a little when put in water. I then tried using a shielding gas (argon and CO2 mixture), and was more successful with that. The end result is still a black substance, but it sparks when it hits water. On one occasion, there was a small amount of white gas given off (presumably hydrogen) as well as a spark that was larger than normal. I found that it was more successful if the electrodes were left in the solution for a longer period of time, but the molten solution had a tendancy to pop and spatter quite a bit. good luck with your experiments Link to comment Share on other sites More sharing options...
jrayj Posted October 26, 2008 Share Posted October 26, 2008 I have also tried this with a basttery charger but had it set up complatly wrong. I am going to try it again as soon as I get some sodium hydroxide. Link to comment Share on other sites More sharing options...
