n the place where I live, there's only sodium nitrate available. But there is also diet salt available in the same grocery store with 70% KCl and 30% NaCl. (cannot buy potassium carbonate or potassium bicarbonate because its not available.

>Planning to dissolve 10g of NaNO3 in hot boiling water in a beaker

>In the same beaker add the 5g of the salt mix

>Then stir it a lot and set to medium heat

But here is waht dont know what to do after, should I:

A) Crystallize the mixture

B) Boil the mixture

C)Pour the soulution in a filter paper

NaNO₃ + NaCl + KCl

You method won't give you much KNO₃.  Furthermore, it will be mixed with NaCl, and NaNO₃, and those are also similar in properties, it will be too difficult to purify.  If you can convince a vendor you're allowed to have it, they would gladly sell it to you.  If you can't justify having it, then you shouldn't have it, by any means.
