« on: October 14, 2015, 12:21:36 PM »
Helo
I try to makr sodium cyanide by heating sodium ferrocyanide with sodium carbonate
When I do this I got a white melted then  when it cooled convert to solid.  I try to dissolve it in water then try to dissolve Gold leafe in the solution.  But nothing happened..
I need a simple method to make sodium cyanide.

The simplest method would be to buy it.  They will only sell it to you if you can prove you can use it safely.  That way, no one gets hurt, and no one gets sued.  The best plan, all around.

Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Just i want to make this post for whos searching about gold dissolving in Cyanide

4 Au + 8(NaCN) +O2 + 2 H2O = 4 NaAu(CN)2 + 4 NaOH

u can make solution of water and NACN 0.05%
but to make this rxn the PH must be 11 at least
and oxygen percentage dissolved in water is very important .. u can add some hydrogen peroxide  H2O2.
