Electrolysis of brine yields hydrogen and chlorine gases and aqueous $\ce{NaOH}$. So is it possible to combine the gases to form $\ce{HCl}$ gas, and mix it back with the aqueous $\ce{NaOH}$, so it returns to brine water?

  • $\begingroup$ Of course. But the reaction of $\ce{H2}$ and $\ce{Cl2}$ would be explosive. The combination is often called Chlorknallgas — chlorine explosive gas — in German. $\endgroup$

  • $\begingroup$ Yes I have seen the individual reactions on Youtube, but I just never saw anyone loop the whole process. $\endgroup$

  • $\begingroup$ I have to know, is this the start of the most ill advised perpetual motion/over unity machine attempt ever? $\endgroup$ Commented Oct 15, 2015 at 3:07
  • $\begingroup$ No, I never thought that this can be an over unity machine from the start. This may be of other uses though. $\endgroup$

  • $\begingroup$ Well there would be no reason to loop the process other than demonstrate that it's possible … $\endgroup$
