Physicsfan Posted June 15, 2010 Share Posted June 15, 2010 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] Link to comment Share on other sites More sharing options...

Physicsfan Posted June 16, 2010 Share Posted June 16, 2010 calcium sulphate is insoluble and will precipitate.What remains is a a solution of potassium nitrate. you can crystallise it Link to comment Share on other sites More sharing options...
