how can we seperate a mixture of potassium nitric and potassium chlorate

Answer 1

How to separate potassium nitrate from mixture of potassium nitrate and potassium chlorate?

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.
