I was tasked with figuring out how to make some $\ce{NH4ClO4}$(ammonium perchlorate). I found that one way of making it was to react potassium perchlorate and ammonium chloride in a double displacement reaction. according to:
$\ce{KClO4 + NH4Cl -> NH4ClO4 + KCl}$
Then I got to work on finding ways of making the necessary reactants without having to buy them by doing additional reactions with easier to find chemicals. After some work I came up with these two reactions:
$\ce{KCl + NH4NO2 -> NH4Cl + KNO2}$ (to make the ammonium cloride)
and
$\ce{KCl + HClO4 -> KClO4 + HCl}$ (to make the potassium perchlorate)
My question is (the newbie part) how should I now go about these reactions? Should I be mixing the reactants together in an aqueous solution? In water? Should I be mixing them into an ionic solution in an electrolytic cell? Or hell do I just mix them together as a granulated form and apply a little heat? How do I get these reactions to occur?
