K2SO4 to KCl

Post by Rodrigo Pires »

Hi there!

i need some help to convert some potassium sulfate into potassium chloride. I thought in this:

K2SO4(aq) + CaCl2(aq) = KCl(aq) + CaSO4(p)

But with this reaction i might end up with some sulfate and calcium contamination in the final potassium chloride solution.
Is there a better method to do this conversion?

Thanks!
