Potassium iodide solution, dissolve 83 g of potassium iodide in water and dilute to 100 ml. Prepare freshly each day. Potassium iodide wash solution, mix 25 ml of 9 N sulphuric acid with 2.5 ml of the potassium iodide solution.
How do you make potassium iodide solution?
Potassium iodide (KI) is prepared by reacting iodine with a hot solution of potassium hydroxide. It is mainly used in the form of a saturated solution, 100 g of potassium iodide to 100 ml of water. This equates to approximately 50 mg/drop. The solution is usually added to water, fruit juice or milk before drinking.
How do you make potassium iodide solution from crystals?
Dissolve KI in about 20-30 ml of distilled water. Add iodine and heat gently with constant mixing until iodine is dissolved. Dilute to 100 ml with distilled water. Store in amber glass-stoppered bottle in the dark.
