  • How to Test for Potassium IodideSciencing

    Such tests form the basis of a number of undergraduate laboratory experiments. No test exists for potassium iodide in the solid state. When it is dissolved in water, potassium iodide separates into potassium ions and iodide ions through a process called "dissociation," and separate tests can be performed for each ion.

  • separation of iodine and copper II in waterYeah Chemistry

    If you have a mixture of solid copper II sulfate and solid iodine, you could get a pretty good separation by mixing them with water. The copper sulfate would dissolve and the iodine wouldn't or almost none of it. The copper sulfate solution could then be separated from the solid iodine by filtration.
