Assuming the given solution is 50% w/w, we add equal amounts of water and KF so as to get the solution in desired quantity.
Take 10 gm oF KI dissolve it in 100ml.
Dissolve 50 g of potassium carbonate in 100 mL of water at 20 0C.
dissolve iodine crystals in a saturated KI(potassium iodide) solution
hehehe
Crystallisation from solution, flotation, or electrostatic separation from suitable minerals.
ask your teacher.

pottassium permangate
add 40g of potassium sodium tartrate to 100ml of water
Dissolve 101.1 g of potassium nitrate in 1 litre of water
it is primary standard........ but before making solution dry it at 120. C
hehehe
I think this is inappropriate for asking on the Internet.
