My Patassium Chlorate isn't good

I have a patassium chlorate cell, it uses platinum electrodes. Ive tried to make chlorate with it 3 times, but what i get dousnt burn very well( it make sugar bubble). could this be the salt im using, i am using deitary salt( which is only 40% KCl ) and some other things.

i can solve this problem in an instant. is your cell running at a hot 80 degrees celcius? do you have a ph tester for tesing the ph? does the chlorate liquid smell of chlorine when running? if it smells of chlorine add some hydrochloric acid to it as it will replace some chlorine lost , most times your supposed chlorate will be halve hydroxide, test the finnished result with a ph test if its nuetral then its clean chlorate, if its caustic add hcl untill its nuetral. the reaction occuring is the generation of chlorine dioxide disovled in water instantly bonding with pottasium hydroxide to form a chlorate. i recomend using pure potassium chlorate though wich is as easy as pie to obtain. all you need is cream of tartart (potasium bicarbonate) and hydrochloric acid ....mix the two together and you have pure potassiu8m chloride. /or you can mix a concentrated strong acid with match heads to make chlorous acid (hlco3) and react this with the bicarb to produce potassium chlorate

This question is two years old and has since been resolved, but thank you for trying to help.

After I filter it I put it on my hot plate for an hour or two. By the time it is done it is one big chlorate mass. Could this be doing anything?

I made some changes to the cell. I got the 12v working and am guessing it outputing 10-12 amps. I placed the cell in an ice bath because the extra voltage was making really hot. I connected about 4 of the PSU's wires together(12v, G) each the wire were also getting to hot. And this time i am using NaCl. I'm going to run it for 2 days since it takes about 26 hours to convert 100g of NaCl to chlorate and I have about 125g.

I'm not using the pool salt, i'm using deitary salt, I just didnt know if the pool salt was KCL.

My procedure go's like this: 1.)make salt solution 2.)put solution in cell and start power supply( 5v) 3.)boil to get rid of hypochlorite 4.)filter 5.)pufiy, by dissolving chlorate in water heating it to boiling point, let cool to room temp, cool to 0 degrees. 6.)refilter Mabye my power supply isnt puting out enought amps, my stupid multimeter broke, I could try useing my dads car battery charger( which has a volt meter and a amp meter). I have a salt water pool so I have those big bags of salt, is this KCl or NaCl.

You may want to double check the contents of that pool salt. Mineral Water mixes often contain metal ions. This is quite bad, since these form insoluble salts under normal conditions, and aren't easily seperate from the chlorate. This is part of the reason I advised raising the pH. Metal Ions can be dissolved by adjusting the pH of the solution up and down. You may want to acidify the salt solution prior to running the electrolysis, since that'd be the only time to preciptitate metal ions insoluible under acidic conditions. This has the added benefit of allowing you to nuetralize the acid with a potassium bearing base (I recomend KOH in this specific case). That'd effectively let you dope the saline solution with potassium prior to starting electrolysis. After boiling to get rid of the hypochlorate, I would recommend adding it back to a solution of KOH. Using KOH will help prevent the Potassium Chlorate from dissolving because of the shared cation, while dissolving metal ion that aren't soluible under any other circumstance (notably aluminum). IF you need a run down on how to make KOH let me know.

There are a few things that could be happening here, and without knowing more about your procedure, I can't really tell you how to fix it. Purely as specualtion, it sounds like you have a very impure final product. There are several things that can be done to purify your end product. Personally, decanting a couple different times in a basic and a nuetral (distilled water) solution would work nicely, though you'll end up with significantly less product then you started off with. Oh, word to the wise: Don't acidify it. You probably know that much but I'd rather sound like an old biddy then have it go splody and not have said anything.
