Chemistry of Alcalic Chlorates

This pages are about various reactions involving sodium or potassium Chlorate. Sodium (I) or Potassium (I) are two very similar ions so let me reffer to both NaClO3|chem and KClO3|chem as Chlorates unless I state otherwise.

Chlorates are powerful oxidisers, mixed with any fuel (like sughar, carbon, celulose), form highly reactive pyrotechnic substances. This Chlorate mixtures explode or burn very fast.

You are at chemistry section.


Afrer fixing connection to the anode , I turned on the chlorate cell again. And added salt water.

The electrical connection to graphite anode broke again. It seems chlorine gas travels through the porous graphite. Why I have not treated it with lineseed oil?

I put molten wax in the anode connection and it works now. And I put excess NaCl on the bottom of my cell. This should keep chloride concentration high and save my electrodes from erosion. A better but more complex method is to re-saturate the liquor continuously as the cell runs. This may be achieved simply by extra solid input material left undissolved on the bottom of the cell. It will be slowly consumed as the cell runs, and will "salt-out" the product and exchange places with it. This complicates taking out the product if you don't run the cell long enough to consume most of the input chemical. However you can simply decant the warm liquor and allow it to cool, taking whatever product crystallises out then re-saturate by pouring it back into the cell. The stuff on the bottom of the cell is replenished when it starts getting thin..

The cell runs at 1.9A smoothly. How much sodium chloride I have to add and when? Gotta warm up calculator!

The graphite rod is eroding quite fast. I have enough of them to last me for some time. I am trying to impregnate the graphite electrodes with oil or wax this time.

Today I had to stop the electrolysis cell. The graphite electrode is broken. I used partly eroded and not treated graphite rod and I already prepared bunch of electrodes so not a big deal. Much of the solid salt already dissolved in. I heated the liquor to dissolve as much as possible and now it is slowly cooling down. Hopefuly some of the chlorate precipitates. However I have not solved the black sludge problem.

The black sludge settled on the bottom of jar. So I poured the liquid to another jar and left the sludge there.

The jar with sightly yellow liquid has been sitting in the freezer for night. Now I see that some crystals formed. Filtering and drying them now.

I poured the liquor back into the cell, added salt and turned the power on. I set it to half power (0.9A) to not to rush anything.

Electric current to the cell misteriously stopped flowing in the morning. I will check the wires later.

I fixed the poor connection.

I put more salt to the cell. Treating the graphite rod with wax and oil helped much. It is almost not eroding while running at 2Amps for 5days. I left the liquor to settle and there was minimal amount of black sludge. The chlorine somewhat reacts with the wax or oil to produce strange smeling stuff.

Someone messed with the power wires going to the electrolyser. The power was cut of around noon. Already fixed.

After a week of operation I left the liquor settle overnight. Now it sits in the freezes and hopefully some of the Chlorate crystals pop out.

I have got a sensible crop of Chlorate crystals. Considering the small volume of the cell is just 0.5l. Added more solid chloride and water and turned on the power.

As every weekend, I stopped the electrolysis extract some Chlorate. I am waiting for the liquor to settle. Them I will put it into freezer.

The cell liquor was in the freezes quite longer than necessary and lot of Chlorate crystalized! Good.

I call a paper soaked in sodium or potassium Chlorate and dryed a Flash paper. This evening I have done some experiments with this paper. I discovered that it does ignite when you hit it hard with a stone. Remember the episode of Mythbusters The exploding panties? Yeah.

I stopped the electrolysis to filter out the sludge from the anode and to get some Chlorate out. Also the anode is sightly eroded by now but I have 8 more and they are cheap. The liquor is too black, so I poured it into a bottle called sedimentator |n.

Sedimentator is a device I use to separate cell liquor to electrolyte and sludge. I am sure there are official names for this device. My version consists of plastic bottle and rubber tube hose. The bottle is filled with suspension which then separates by gravity. A tube is attached 2cm above the bottom of the bottle. The tube is used to deacant the liquid, leaving the sludge in the bottle. Depending on the practicle size the process takes all night.

I plan to make another electrolysis cell. My power supply has 6v and 12v setting. With the 12v setting I will be able to run the two cells connected in series. The will be faster that way.

Tento raz toho oveľa viac. Dokonca som musel rezervovať väčšiu nádobku. Bude z toho ohňostroj. Haha.

I did experiments with the mix of Chlorate and fuel. It burns fast with bright flame. For the another experiment I just mixed tiny pile of coarse Chlorate crystals with tiny pile of sugar on old ceramic pot and ignited with a flaming stick. It burned bright and very east even so coarse. The pot didn't core with the high temperature and after three seconds of quietness shattered throwing shrapnel everywhere. Luckily me was inside room and watched the experiment thru window.

The cell was running for a week, then I was forced to stop it. I already prepared electrodes for two cells. I am busy at school, so it wont happen till next week.

Lots of Chlorate crystalized overnight. It is more black because I didn't have time to wait for the liquor to settle enough.

The cell is now running with the second anode, I waxed yesterday. Hope it will last long and give me lots of Chlorate per week. The second cell is waiting half finished, because I cannot remember where I put an copper wire, to make negative electrodes from.

I milled the Chlorate crystals in my ball mill with steel balls and the results are amazing. After a day I got fine powder. To mill aluminium, lead balls are better however.

The first cell is running again with new anode and the second is almost done. Me is missing a piece of copper wire for the cathode. Aluminium can not be used because it forms complexes in alcalic environment that forms in the cell.

The Chlorate crystals are too big to be used in compositions. I cleaned my ball mill of aluminium powder. It is now milling the Chlorate crystals with lead milling media.

You can not mill Chlorate crystals with lead balls. The Chlorate crystals mill the lead balls. The test batch is black of lead and useless. I dissolved it and put into the bottle for junk electrolyte.

I can not find suitable copper wire for cathodes for the second cell. But. The cell no1 needs harvest, so I just fliped over the anode and cathode to the second cell. This way I do not have to stop process to get the Chlorate out. When the first cell is extracted, the second is ready for extraction and the other way around.

Not much precipitated from the no1 cell. It was about a week the no2 started. I do not think much will fall out from it, but I am going to try.

Usual amount of Chlorate precipitated in the freezer from the cell no1.
