L/O/G/Owww.themegallery.comSynthesis of KNO3
KNO3Pottasium nitrate salt can be made by react Potassium Chloride (KCl) with Sodium nitrate (NaNO3)If both of those saturated solution being mixed, then will formed sodium chloride (NaCl) and potassium nitrate (KNO3)
Observation DataColor and Structure of KCl: White, Solid PowderColor and Structure of NaNO3: White, Solid PowderColor and Structure of KNO3: Colorless, Liquid and White, solid
KNO3Figure 1. Graph of temperature and solubility of salt(Inorganic Chemistry Lecturer Team, 2015)
KNO3We cool the solution to decrease solubility.After cooling, then will form KNO3 crystal with have white color and structur crystal like needleThen recrystalization with hot water
Observation DataThe Reaction Occurred:
KCl(s) + H2O(l)KCl(aq)NaNO3(s) + H2O(l) NaNO3(aq)KCl(aq) + NaNO3(aq) KNO3(aq) + NaCl(aq)KNO3(aq) KNO3(s)Observation DataWeight of KNO3 crystals produce:0.965 gram
