Hi there

I only know a bit of the basic's of chemistry and would like some help please.

Im trying to make some potassium nitrate (Kno3), just wondering if it can be extracted from sulphate of potash, which says it has
1. Potassium as Sulphate 41.5% and
2.Sulphur as Sulphate 17%

This would be a good source of potassium am i right??
Now where could i get some nitrate but must be from somewhere around the house?

Aswell what would be the best method to extract the kno3 at the end?

Thanks

you can also buy it from ebay

what do you plan on doing?

I know were to buy it thanks for that... what i really want to know is how you can make it using items found at an average house hold. I have sulphate of potash. So the question is can i make kno3 using sulphate of potash and something found at home containnig nitrate??

What would be the method for mixing and extracting these two mixtures

It's not really practical.

Then what other ways is there to get some kno3. I live in Australia and it cant be bought as a stump remover, cant be bought from a chemist, cant be bought as a fertlizer. Are there any other alternatives for extracting kno3 from easily found products.

I want to make a smoke bomb and maybe some gunpowder. Is a stone mortar and pestle ok for mixing?
