Iodine solution is a commonly used laboratory reagent that is used to test for the presence of starch in various materials. It is also used in medical applications such as disinfecting wounds and as a supplement for people who do not consume enough iodine in their diet. In this article, we will discuss how to make iodine solution from potassium iodide.
To make iodine solution from potassium iodide, you will need the following materials: – Potassium iodide – Distilled water – Iodine crystals – Glass beakers – Glass stirring rod – Dropper
Step 1: Dissolve potassium iodide in distilled water. Add 10 grams of potassium iodide to 100 ml of distilled water in a glass beaker. Stir until the potassium iodide is completely dissolved. Step 2: Add iodine crystals to the solution. Add 7 grams of iodine crystals to the solution and stir until the iodine is completely dissolved. Step 3: Dilute the solution. Add another 100 ml of distilled water to the solution and stir until the solution is completely mixed.
Iodine solution should be stored in a dark bottle to prevent light from breaking down the iodine. It should also be stored in a cool, dry place. If stored properly, iodine solution can last for several months.
Iodine solution is commonly used in laboratory settings to test for the presence of starch in various materials. It is also used in medical applications as a disinfectant for wounds and as a supplement for people who do not consume enough iodine in their diet.
Iodine solution should be handled with care as it can be toxic if ingested or if it comes into contact with the skin. It should also be kept away from heat sources as it is flammable.
In conclusion, making iodine solution from potassium iodide is a simple process that can be done in a laboratory setting. It is important to handle iodine solution with care and store it properly to ensure its longevity. With these precautions in mind, iodine solution can be a useful tool in both laboratory and medical settings.
