Thread: WHY has this not changed everything??

Apologies Marvo, I was responding to Mario and didn't realise you posted.

In response to what you said; there's not really such a thing as 'practically impossible' in science... lots of zeros may make a number look small but all this means is that you need to increase various variables which typically allow for huge variation; for example, in this circumstance there's no practical reason you can't just increase the voltage a thousandfold with a transformer.

If it was 'practically impossible' for pure water to conduct electricity, then how do we get hydrogen from electrolysing water; something which is most definitely possible?

Salt water conducts a lot easier because it just electrolyses the salt ions instead of the hydroxide and hydrogen ions, which are much more abundant in the solution.
