to make potassium chlorate from bleach and potassium chloride, can i use potassium sulfate as a substitute? Answered

currently i am exploring lots of different ways to make potassium chlorate, and i would like to know, in nurdrages instructable which makes potassium chlorate from bleach and potassium chloride, would it be possible to use potassium sulfate instead, as i can easily get potassium sulfate in large amounts cheaply.

the reason i am asking this is because in other sites which have otherwise proved unreliable, there have been instructions on using calcium hypochlorite and either potassium chloride, carbonate or sulfate as the donor, instead of just chloride. and so i would like to know if this method works with potassium and bleach method as done by nurdrage

potassium chloride is easily obtainable as well. You just haven't found it yet.

You know, experimenting with highly energetic chemical reactions using homemade chemicals of undetermined purity is particularly foolish. There are plenty of suppliers who will sell you enough chemicals to blow yourself to tiny pieces (doesn't even require BATF licenses for that much.) Can't buy them because you're too young? Enlist your parents. Can't get your parents to condone/assist your activities in this area? Then you probably don't have a safe environment to be performing the experiments.

yes, i know it is, however, potassium sulfate is cheaper , as it costs $7/kg, wheras potassium chloride here costs $15/100g.
so you understand my logic?

KCl is widely available as a sodium-free charge for water softeners. About $0.50/lb from Amazon in the US. Also as "sodium-free salt" in grocery stores for those with high blood pressure. Much more expensive, of course, but not $15/100g.
I think the problem with the sulfate is that the resulting sodium sulfate and potassium chlorate have similar solubilities, which makes them hard to separate.
Sodium Chloride is MUCH more soluble than potassium chlorate.

If you want KCl , you can make by wood ash that is rich of Potassium Carbonate..
You should filter a solution of hot water and ash using simple coffee filters..
When the filter water evaporates , you can see a white powder or crystals of Potassium Carbonate(you may test it using a flame , if the flame turn in purple it's ok!)..
Now you should add HCl at powder to form Potassium Chloride(KCl) and water..
