nitrate, KNO3, by using potassium carbonat? A Web site on fireworks provides directions for preparing potassium nitrate, KNO3, by using potassium carbonate and ammonium nitrate according to the following equation:
K2CO3 + 2 NH4NO3 -> 2 KNO3 + CO2 + H2O + NH3

The directions claim that one should “mix one kilogram of potassium carbonate with two kilograms of ammonium nitrate. The carbon dioxide and ammonia come off as gases, and the water can be evaporated, leaving two kilograms of pure potassium nitrate.” Use information from this lesson to evaluate the claim. (10 points)
