sodium chloride choice for perchlorate


I've recently ordered a titanium substrate lead dioxide anode from alibaba and it will arrive soon. I'm planning to make a sodium perchlorate cell and let the cell run directly from sodium chloride to sodium perchlorate. I still have to buy sodium chloride, I've read regular table salt doesn't work because of the iodine, but I've found vacuum salt on the internet that's really cheap and has does not have iodine. However this salt cointains the anti-caking agent sodium ferrocyanide. Will this anti-caking agent interfere with the electrolysis or have a negative effects on the elctrodes?

I do not know about vacuum salt and sodium ferrocyanide, but many grocery stores sell "free flowing salt" which is ~98% NaCl with the remainder being an insoluble anticaking agent like sodium aluminate, no iodine. I do not know how you would remove the anticaking agents because they have an incredibly small particle size, but I do not think they would interfere with the reaction.

Recrystallization worked for me, small particles settle on the bottom of solution within a day or two. decant, reduce water vol. and crystallize! Good luck!



I am grumpy because I moved and my "lab" is no more, and all the chemicals are waiting for me in a few boxes far far away from my reach. *tear*

If you get to the result - you can't be doing it wrong!

Try canning & pickling salt, cheap and has no anti cake or Iodine.





Boom.
The explosion removed the windows, the door and most of the chimney.
It was the sort of thing you expected in the Street of alchemists. The neighbors preferred explosions, which were at least identifiable and soon over. They were better than the smells, which crept up on you.
-Terry Pratchett, "Moving Pictures"

It is essential that persons having explosive 
substances under their charge should never 
lose sight of the conviction that, preventive 
measures should always be prescribed 
on the hypothesis of an explosion.

Marcellin Berthelot - 1892 Explosives and their power - Page 47

I believe kosher salt contains no iodine, and depending on the brand, may not even have any added anticaking agents. I’m not sure on the levels of other minerals though, you’ll have to check that yourself, but you should be able to find it in local stores.



In chemistry, sometimes the solution is the problem.

Dishwasher or water softener salt is probably available at your local supermarket. It has no additives.
