hi there, is it possible to obtain ammonium perchlorate from mixing ammonium nitrate with potassium perchlorate.

i know that the k perchlorate is low in solubility but unsure about ammonium perchlorates solubility properties.

in theory it should work ( i think, if chemistry has tought me anything)

i believe the chemical equation for the reaction would look like this;

KClO4 + NH4NO3 -----> KNO3 + NH4ClO4

as both potassium and ammonium ions carry a charge of 1+ and that potassium nitrate is very soluble.

any help would be much appreciated, thanks.

Well, the reaction would work and it's correctly ballanced. Your chemisty classes are well paying off

Your problem would be to separate the AP from the resulted potassium nitrate, as they have similar solubilities.

Also, wiki it's faily good at solubilities of different chems for a quick check up.

cheers m8,

You might get scuppered by the minimum solubility law - reactions tend to go in the direction that forms the least soluble species, which in this case is definitely pot. perc.

As pyrotrev said, because potassium perchlorate is so insoluble, the perchlorate added by the ammonium perchlorate will force potassium perchlorate out of the solution, not vice versa .
It's also called the common ion effect if you want to look it up.
