Synthesis of Potassium Nitrate

Here I create potassium nitrate by a simple double replacement reaction involving ammonium nitrate and potassium chloride:

NH4NO3 + KCl == KNO3 + NH4Cl

These are then separated by cooling the solution in an ice bath, causing the KNO3 to crystallize into beautiful long spikes!

Theoretical amount of KNO3 produced in this reaction was 63.1g, but I only recovered 31.4g. This shows that this is a rather inefficient process, and only gave me a 50% yield.
