  1. As a matter of facts, I actually pulled of this exact reaction just the other day. I wanted to make KCl by mixing 30% w/w hydrochloric acid, with solid KNO3. This resulted in an endothermic reaction, producing the ions you also mention in the above postulate (K⁺, Cl⁻, NO3⁻ and H3O⁺). However, it is possible to seperate the KCl by recrystallization. I reacted 100mL 30% hydrochloric acid with 83g of powdered potassium nitrate, yielding about 45g of crude KCl after crystallization. I don't know though, what the complete reaction should look like! Under the reaction I found that nitrogen gas was produced as well, but what actually remains in the mother liquid, I don't know...:| Maybe, it is a weak solution of "aqua regia"? regards Hey! Thanks for this reply dude.. really helped me out a lot! I got to a pale yellow liquid after adding aqeous HCl to KNO3.. I wanted to produce KCl, which I also did.. I used slow heating during the crystallizationprocess.. When combining hydrochloric acid with potassium nitrate, an endothermic reaction occurs, and N2 is released.. as long as no heating is applied, I think you would be in the 'safe zone' here:) Regards
