KCl

[KaBoom]

So KCl can be found in salt substitute, but the only salt I have found it in has a 66% to 33% KCl to NaCl ratio... Is there anyway I can separate out the 2 chlorides or is it easier/more practical to just to look for another source of KCl?

But really... if your trying to go for chlorates via electrolysis, you can learn with plain NaCl or KCl... it really doesn't matter unless you want good colors... in which case ABSOLUTELY FUCKING NO NaCl should be present. :rant:

How practical trying to separate out the salts is... will be dependent on your application... and how tolerant of sodium contamination it is.

EDIT: Easiest solution. Just fucking buy potassium chlorate if thats your goal.

Perhaps you could find out which is the heavier ion and somehow hope that one would sink to the bottom of solution? Of course that is going to be real hard to do because they are both very ionic and will not like coming out of solution

It might be possible to extract KCl from NaCl by recrystallization from water. If you look at KCl and NaCl on this graph (http://sciencegeek.net/Chemistry/taters/graphics/solubility.gif), you can see that cooling a saturated solution precipitates more KCl than NaCl.
That being said, it's very cheap and can be bought in large quantities easily as a water softener. I have bought this product (http://www.homedepot.com/Appliances-Water-Dispensers-Filters-Water-Softeners/h_d1/N-5yc1vZ1xilZaq3y/R-100351743/h_d2/ProductDisplay?langId=-1&catalogId=10053) at Home Depot. Try looking around pool shops and hardware stores for water softener.

I was going to say idiot, but the reality is he probably hasn't taken chem yet, so it's really not his fault, thus idiot would be too harsh. Google ionic equilibrium in solution.

"hasn't taken chemistry yet"... to what standard do you call "taking chemistry" A-level? Degree? Post-grad? Just because my chemical knowledge may not be as advanced as yours, you think I am a complete retard that has never studied chemistry to any reasonable level?

I think my best bet is just to try and get hold of some water softener; thanks for the help.

Surmising that one ion is heavier than another and will therefore sink in solution is pretty fuckin' stupid. And yes, it indicates that you've never had a chemistry course in your life. But that's okay. We were all pretty fuckin' stupid at one point. Although this is a rather innocuous case, in BB (or whatever the acronym is these days), try not to postulate anything that can get someone hurt. If you don't know, say so. Making stupid mistakes will get you hurt, so do your homework first.

Anyways, just buy it if you need it pure. You CAN do chlorate electrolysis with both, IIRC. There used to be a spectacular website on chlorate cells, but I can't seem to find it anymore. All my good pyro websites have gone offline over the years, and aren't in the internet archive. :mad: should've saved em when I had the chance.

Does anyone else remember this site? it was incredibly detailed, and had info on chlorates, perchlorates, the effects of temperature, different anode and cathode materials--EVERYTHING! It was great! It might have been here: http://users.foxvalley.net/~chemengr

IIRC the hosting is running out on it soon, or already did. It had cape Canaveral in the url IIRC.

First off, I never said a word about you. Unless you also use the account Uber_Apples. Then yes I was talking to you, and the quote below nicely explains why. The "this man" in the passage you quoted was in reference to the guy I was quoting, Uber_Apples.

Hydorponichronic, my apologies, I misunderstood what you had written, thanks for you help on this topic...:thumbsup:
