Bill,
I dunno about why washing soda but I suspect it is a chemical thing under
electrolysis. Washing soda is Na2CO3 - Sodium Carbonate.
Salt is NaCl - Sodium Chloride. Mix it in water and run a current through
it and you might get hydrochloric acid and/or free chlorine gas which are
some pretty nasty things to deal with. Sodium isn't anything to mess around
with either.
With washing soda you'd get Carbon Dioxide and Sodium Monoxide or something
like that. No where near as nasty as the Chlorates!
I don't know how this would work, but I remember enough chemistry to think I
don't wanna mess with even a slight chance of these Chlorate compounds.
Cheers!!
Jim
