Should i use potassium iodide or iodine crystals or both of them?
You should use iodine to prepare 0.6 mM iodine solution.
Thankyou so much for your help.
Debasis is correct if you are trying to make a solution as you wrote it above, but just to make sure we understand your question: Are you trying to make an iodine solution or an iodide solution? If the former, then definitely use I2 If I-, useKI.
