Re: Is it safe to electrolyse water and cream of tartar?

Dear Nadeem;
I can think of no hazards resulting from the electrolysis of cream of 
tartar. I am assuming that the source of electricity is low [say, 20 
V]voltage DC, and your work area has good active ventilation.

Most substances found about the house and kitchen can be electrolysed 
without concern if small amounts are used.  But note that even ordinary 
table salt [NaCl]when electrolysed will yield chlorine, hypochlorite, lye, 
etc. depending on the experimental set-up. These are all harmful chemicals, 
but with good ventilation, small quantities of NaCl,and reasonable care 
there should be no harm. I did this last myself when I was in high school. 
I suffered no harm.

BUT - always check with someone knowledgeable before you act.
