how pure can potassium chlorate be made from sodium chlorate and what is the best method to do so?????????/

yes, sorry , i meant let the fumes ( vapours ) from the ammonium hydroxide flow over the top of whatever you have made the hcl in. then the clouds of ammonium chloride should appear. i did the experiment after all, i did it outside with safety clothing and stuff. but i would suggest if someone else try it, get your hands on a 2 litre boiling flask, a glass funnel, a clamp and stand, a controllable flamming heat source, and the correct connections from your reaction vessel to the collection vessel. i tried it without these things and tasted gaseous hcl ( not nice) , as the retard that i am, i used a 2ltr plastic coke bottle some garden hose a glass jar and some electrical tape, so i guess i deserved the lungfull of acid gas,but at least i know it works and how to do it properly next time. Merged post follows: Consecutive posts mergedwould the gas evolved be able to be condensed into a concentrated form if it were in the presence of enough moisture?? what i was thinking was, to perform the NaCl and H2SO4 as somebody else and i suggested previously, and symaltaneously boil some water in another flask and connect the tubes from both vessels to a condenser. any help on this would be much appreciated. thanks.

add conc sulphuric acid to NaCl and heat. bubble the gas through H2O and roberts your fathers,sisters brother. test it with conc ammonium hydroxide white mist of NH4CL should appear. hope this helps, i havent done it yet but i will be trying it soon.
