It's probably going to be cheaper, easier, and a heck of a lot less messy to just go to the drugstore and buy it, but if you're really insistent on looking for a process you could theoretically do at home, the historic method was extraction from animal feces (yes, really). Hypothetically you could make it from nitric acid and potassium hydroxide, but if you can't find a place to buy potassium nitrate your chances of getting your hands on either of those are pretty low.
KNO3 is the chemical formula of potassium nitrate.
potassium nitrite
Potassium nitrate is composed of about 38.7% potassium.
Potassium nitrate is KNO3. There is one potassium per one nitrate. One mole of potassium nitrate contains one mole of nitrate.
In order to form a potassium nitrate solution, the ionic bond between potassium ions and nitrate ions in the solid potassium nitrate compound needs to be broken. This allows the potassium and nitrate ions to separate and become surrounded by water molecules, resulting in the formation of a potassium nitrate solution.
KNO3 is the chemical formula of potassium nitrate.
Potassium nitrate = KNO3
Technically, yes. Potassium nitrate is a potassium atom attached to the nitrate ion.
