Separating calcium and potassium chloride salts


GadgetBoy

Recommended Posts

So, I'm an electronics technician, so my knowledge of chemistry is limited to some rudimentary knowledge regarding battery chemistry and electrolytic capacitors.

 

So, I need some calcium chloride to raise the density of water to do a glitter lamp, but it's expensive to order online. I can, however, get desiccant at the local hardware store, which contains a mix of potassium and calcium chloride. Is there a simple way I can separate the two?

You might not need to do the separation as such.

Keep adding the mixture of chlorides to water until you get a solution which is dense enough. The potassium chloride won't do much harm .

You may need to filter the solution or let it settle to get rid of suspended particles.
