Lepton (1/13)



  1. I've been searching around for a while now and I haven't had any luck in finding an efficient method of creating pure bromine liquid. Any help would be much appreciated.
  2. In my opinion, the simplest way to make relatively pure Cl2 gas is to obtain MnO2 from a zinc-carbon battery (its that brown-black paste-like stuff between the outer shell and the carbon electrode), pour in a little hydrochloric acid, and set up a simple apparatus in order to bubble the Cl2 gas produced through some water into a test tube. Voila. Isolated chlorine gas. The chemical equation of this reaction is: 4 HCl + MnO2 → MnCl2 + 2 H2O + Cl2 For those of you who are curious, this method of creating chlorine gas was actually how chlorine was discovered. It was discovered in 1774 by Carl Wilhelm Scheele.
