Title: Do we get the same amount of water from burning electrolysed water?
Post by: ohm on 07/02/2009 12:30:02

ohm asked the Naked Scientists:
   
If you electrolyse 1 gallon of water into hydrogen and oxygen and then run
the hydrogen through a fuel cell, will the process return/produce 1 gallon of
water, and how quick is the process?

What do you think?

Obviously you get the same amount of water, in ideal conditions; in practice not, because of loss of substances during the experiment (some water will vaporize during electrolys, some of the gases will be lost in the athmosphere before you recombine them, ecc).
