i understand now why titanium is used for anode. as the mmo wears away,the titanium is exposed and titanium passivates when used as anode so it does not conduct and therefore wont erode leaving only the mmo coating as conductior. this came to me as i was thinking of using the platinum coated discs from my apple g3. any scratch on the disc will just give way to almost instant erosion, if it is even platinum.(damn freakin space bar on my apple keypad sticks like crazy)

My cell is going good but i think I will attemp Calcium chlorate cell soon , Dan2 does your anode made from tin/antimony solder make residu in the solution ?

I will probaly make KClO3 but the kclo3 source I found cost my 7$ for 312g so it is a little to high.




I never asked for this.

The Tin Oxide Anode does not leave any residue but it appears to be no good at making anything even though it lasts a long time.

I liked the article. I might try it.

plante i am using hi-yield brand muriate of potash. it is dirty as hell with some red clay stuff but i have made chlorate with it before. you just have to filter it and you get more than three pounds of it for your 7 dollars. something is wrong with my 5volt output wire because it gets too hot too quick and too bad because as it gets hot and starts bubbling i can see it making instant chlorate plumes.i got one mean,mean,nasty punch out of the wet anode when i had it on 5volts.

How will you deal with the calcium hydroxide buildup on the cathode?

how about using ice melting salt?some have potassium chloride,sodium chloride,calcium chloride and urea.

I will scrap it of in the solution time to time .

When y go see my cell it was realy acidic and a lot of crust was on the cathode....?

I just started a KCl to KClO3 cell. Dan 2 : Why it does not make anything?

Im sorry if its a bit of a change of subject but this forum post is on chlorates so i though i could quickly ask this...

What type of Oxidizing agent should be used to oxidize Calcium Chloride to Calcium Chlorate?

ChemistryAlchemist isnt voltage what does that or is it amperage? speaking of amperage(ha ha), is amperage what makes my chlorate cell melt the epoxy and cap? i am running of a computer power supply and have to use the 3 volt lead because the 5 volts will just get too hot after 2hrs. my electrodes are about 1/2 inch apart. 3 volts is just too slow. i would like to run at 5volts but want to know if there is a way to drop the amperage on my 5 volt leads? arent there inline amperage lowering thingamajiggers that can be added?my other cell is doing better with an old 6volt 250ma charger.somewhere i saw that a person used a car battery charger with a nichrome heating element coil to reduce voltage. if one lowers voltage with a nichrome wire,wont amperage drop too?

On the wiki page it said that you can use a oxidizing agent...

"It can be formed by oxidation of calcium chloride by a strong oxidizing agent."

Reeves, you can try adding some more space between the electrodes first. If that isn't an option, why don't you build another cell and connect it in parallel?

Nichrome wire - any resistance, really - will dissipate (waste) some energy as heat. You might as well put it to good use by adding another cell in parallel, IMO.

ooh! thank you tank. you are certainly correct about the waste and i just happen to build another cell.parallel would be jumping from the neg in #1 cell to neg in #2 cell with a jumper wire and likewise pos to pos? i never would have thought of doing that even though i now recall reading your post on a similar matter before. series would be neg from#1 cell to pos in #2 and neg in #2 cell to pos in#1 cell ?

I just saw a video on youtube about making a 250ml solution of water with 90 grams of iodized salt and placing a 9 volt battery in the solution and leaving it... it produces Sodium Chlorate... is this true? i know its made by electrolysis but can this method be true? Is it a safe method of making it?

I guess the best way to find out is try it it's pretty simple i'm going to do it when I get back I like your you tube on producing Naoh by electrolysis

Yeah i guess i could check it out, no harm in trying i guess... can you over electrolysis it... if u know what i mean... yeah thanks for checking it out :)

I might be wrong as it is decades since I did any electrochemistry but;

According to this a 9V battery is good for about 300 to 600 mAh

http://data.energizer.com/PDFs/522.pdf

Let us assume that it is 600mAh ( best case scenario )

Then it will produce 2160 Coulombs

http://en.wikipedia.org/wiki/MAh

Using Faraday's 1st law

http://en.wikipedia.org/wiki/Faraday%27s_law_of_electrolysis

I make it that the best case yield is 0.79g of chlorine or 11 millimoles of molecular chlorine!

It requires 3 moles of chlorine to make 1 mole of sodium perchlorate so assuming 100% yield we would end up with around 1.17g.
