Edit: The chemical equation I included for the disproportionation reaction of calcium hypochlorite is incorrect. There is no hydrogen in calcium hypochlorite (not sure how I made such a silly mistake) and so hydrogen gas is not released in this reaction.
It had thay sodium color during the burn.. but that could be what is actually burning in the chlorate liquid.❤
Was the sugar and potassium chlorate mixed or was the chlorate on top in the test tube before you added the acid? The bright yellow colour at 3:26 is interesting, it looks like you may have formed some chlorine dioxide, though if your powders were well mixed it is just as likely some degradation product from the sugar.
They were mixed, but definitely not thoroughly at all. I think you may be right that was likely chlorine dioxide, I've formed that a few times in the past on accident by the action of sulfuric acid on chlorates in the presence of a reducing agent. Usually it's oxalic acid but I guess regular sugar works too if used in large excess the way I did here
Kind of crazy that the KClO3 is the least soluble salt in solution. Calcium salts are usually very insoluble whereas potassium salts are usually very soluble. On top of that, NaClO3 is extremely soluble around 3 times as soluble as NaCl. So it seems very strange that KClO3 is a quarter as soluble as KCl.
I agree 100%
What I've found is that calcium salts tend to be super soluble when they're bound to two -1 anions and super insoluble when they're bound to a single -2 anion. Potassium salts in general seem to be less soluble than sodium salts, and also seem to fluctuate solubility more with temperature.
Just a general observation that definitely doesn't always hold true. Definitely something I noticed myself.
can you swap the calcium hypochlorite with sodium hypochlorite?
You could, but considering the easiest source of that is bleach you'd be working with an immense amount of volume to get a similar yield.
☠️☠️☠️Bro.. Wasn't it much way easier just to add Potash (K2CO3) to get Calcium carbonate and just filter it. It will had much more yield than adding KCl.
What about seperating calcium carbonate and potassium chlorate ? (Both are insoluble when water is cooled down) then you will have to get hot water and seperate potassium chlorate (being more soluble at high temperatures) making the process more complex
The stoichiometry was wrong, there's no hydrogen in hypochlorite.
Yeah I corrected that in the video description.. I have no idea why RUclips doesn't let you make in-video text blurbs or edits anymore.. it would be very useful for how often I screw up.
