   tells me this for 5%:  Dissolve 10 g potassium iodide in 100 ml of distilled   
   water. B. Slowly add 5 g iodine crystals, while shaking. C. Filter and store   
   in a tightly stoppered    
   brown bottle. Take care: The reaction is exothermic (emits heat).   
      
   Another option is to dissolve iodine in ethanol.   
   It is not clear, what solvent is expected for the testing.
