Accelerating electrolysis of water without killing an entire class of students
Hi !
I wanted to present water electrolysis as an introduction to explain chemical changes in opposition of physical ones. With an Hofmann voltameter, it seems pretty easy recovering 2H+ and O-, but some website advise to add salt as an electrolyte.
So, maybe very dumb question, but how adding salt didn't make it a NACL solution, potentially resulting of gaseous dichlore after electrolysis ?
