How do you separate potassium nitrate from potassium oxide?

Answer 1

Yes. If you mix it with a metal that is higher on the Activity Series of Metals, that metal will replace the lower metal. In our case, Lithium is the only element that is higher than potassium. So, the Lithium would replace the Potassium, forming Potassium and Lithium Nitrate.

Answer 2

Cool the mixture to nearly 0c and the KNO3 should precipitate. Potassium nitrate will settle out of the water as it gets colder. you wont be able to remove all of the potassium nitrate form the water this way. But you will bet nearly all of it. If you want the rest you can boil down the liquid and cool it again and more will precipitate. but not much more. The remaining water could be let to evaporate and the stuff left should be potassium nitrate but if there were other contaminants left these will be in there too.

Answer 3

wll that's a very hard thing to do because you cant just mix the mixture with water and boil it off because for that to happen you would need to have a solid and a liquid but the only other option you have is to use density for example the density of potassium chlorate is 2.34g/cm3, and the dinsity of potassium nirate is 2.10g/cm3 . now there are two things you can do you can find a liquid that has a density of 2.15g/cm3 (search Google) then put your powder slowly and carefully the floting remains should be potassium cholride so scoop of the top, drain the water and let both to dry. another simpler method is to see how much of the mixture you put in for example 5g of potassium nitrate, and 7g of potassium chlorate, then you would just shake or vibrate the mixture for a while and then scoop out 7g from the top which should be potassium chlorateand 5g from the bottom which should be the potassium nirate. *Your welcome*

(these are two theoretical ideas of mine and only mine, and you must beaware that i did not try this but in theory it should work)

Answer 4

Potassium nitrate and potassium oxide have different solubilities in water. You can dissolve the mixture in water, where potassium nitrate will dissolve and potassium oxide will remain as a solid. Then, you can filter the solution to separate the potassium nitrate in the dissolved form.

Answer 5

Potassium nitrate is solid and Lead chloride is found as aqueous solution

so these could be easily separated out.

Answer 6

Potassium oxide doesn't even contain the correct molecular formula for potassium nitrate to be "seperated" from it. Potassium oxide is K2O. Potassium nitrate is KNO3.

Answer 7

Evaporating the water potassium nitrate remain as a crystallized residue.

Answer 8

Fractional Crystallization.

Answer 9

Yes
