@TerminalRhinoVirus He was using a salt bath . . .almost certainly NaCl, which melts at 800C+ and boils at about 1400*C. Consequently, the thermal decomposition of water is not relevant as the bath would have long evaporated before such temperatures were reached if he had some kind of magic hotplate.
Artificial fluoridation of water is a hot issue. When hexafluorosilicic acid is added to water then the water is evaporated, what is left? Will distilling water as seen here result in pure H2O, or will fluorine gas follow the water vapor and be condensed with it? Is the distillation of tapwater dangerous because of the fluorine gas that may be released? Or will all the fluorine be left behind as a solid?
@TerminalRhinoVirus No I did not, but I felt is wasn't really an issue here as (a) it would be almost imposssible for a hotplate to reach this temperature without it being only something Bill Gates himself could afford, and (b) salt melts at some 800C odd.
It's just that you didn't know what you were talking about. Water is perfectly safe to distill at home. Plus, this is the internet, you should automatically expect rudeness.
@TerminalRhinoVirus Then your aunt is wrong. The only real way the hydrogen can come out of the water is by electrolysis, which will certainly not happen here. Distilling water is quite safe . . .search RU-vid and you will find people distilling concentrated acids and such, and carcinogens such as benzene and aniline are also commonplace. Please read up before posting, as you are clearly inexperienced in the field.
