Yes.

 

react an aqueous solution of [ce]K2SO4[/ce] with an aqueous solution of [ce]Ca(NO3)2[/ce].

 

through a double displacement reaction,

[ce]K2SO4 + Ca(NO3)2 -> 2KNO3 + CaSO4 v[/ce]

how to seperate the KNO3 and CaSO4? I'm afraid that both can't be seperate

[Physicsfan]

calcium sulphate is insoluble and will precipitate.What remains is a a solution of potassium nitrate. you can crystallise it

Cool, Thank you.
