How do you make potassium iodide solution of known concentration?
- Dissolve 40 grams of potassium iodide in 100 ml of water.
- Dissolve 15 grams of Iodine in the above solution.
- Add 3 drops of dilute HCl.
- Finally make upto 1000 ml with water.
Why do we use potassium iodide in an iodine solution?
- Starch give deep blue color which is helpful for detection of endpoint.
- Starch made complex with iodide when heated with water decomposition occure ,beta-amylose formed which combined with iodine to form starch/iodine complex of highly intense color.
- Freshly prepared starch is used because it is biodegraded.
What are the side effects of potassium iodide?
Side effects of KI (potassium iodide) may include stomach or gastro-intestinal upset, allergic reactions, rashes, and inflammation of the salivary glands. When taken as recommended, KI (potassium iodide) can cause rare adverse health effects related to the thyroid gland.

How do you make saturated potassium oxalate?
How do you make potassium oxalate? Potassium ferric oxalate is prepared when freshly prepared ferric hydroxide is dissolved in a solution of oxalic acid, yellow precipitate of ferrous oxalate will be formed. It is further treated with potassium oxalate monohydrate, a green precipitate of Potassium Ferric Oxalate is formed.
How is a saturated solution created?
A saturated solution is prepared by continuously adding solute to the solution until a stage is reached where the solute appears as a solid precipitate or as crystals to form a highly saturated solution.
How do you make potassium iodine solution?
Potassium iodide solution, dissolve 83 g of potassium iodide in water and dilute to 100 ml. Prepare freshly each day.
How do you make a saturated solution at home?
How to Make a Saturated SolutionStir solid solute into a liquid solvent.Keep adding solid until it stops dissolving. This is when solid starts accumulating in the liquid. Usually, the solid is more dense than the liquid and sinks.The liquid contents are a saturated solution.
How do you make a saturated aqueous solution?
Here are three ways to make a saturated solution:Add solute to a liquid until no more will dissolve. ... Evaporate solvent from an unsaturated solution. ... Add a seed crystal to a supersaturated solution.
What is saturated potassium iodide solution used for?
Saturated solution of Potassium Iodide (SSKI) is used pharmaceutically for emergency use in patients experiencing acute symptoms of severe hyperthyroidism (also known as thyroid storm or thyrotoxic crisis).
What happens when potassium iodide is dissolved in water?
0:321:19Equation for KI + H2O (Potassium iodide + Water) - YouTubeYouTubeStart of suggested clipEnd of suggested clipHere plus liquid water when we put the solid into the liquid it dissolves into its ions itMoreHere plus liquid water when we put the solid into the liquid it dissolves into its ions it dissociates. So we can write k. Plus that's the potassium cation.
How do you prepare saturated and unsaturated solution?
By heating the solution a saturated solution can be altered into an unsaturated solution. Without adding any solvent it can be changed into an unsaturated solution. An unsaturated solution contains less than the maximum amount of solute that can be dissolved at that temperature.
What does saturated solution mean?
A solution in which the maximum amount of solvent has been dissolved. Any more solute added will sit as crystals on the bottom of the container.
How did you prepare a saturated solution a supersaturated solution?
A supersaturated solution contains more dissolved solute than required for preparing a saturated solution and can be prepared by heating a saturated solution, adding more solute, and then cooling it gently.
How much salt does it take to make a saturated solution?
The solubility of sodium chloride or table salt is only slightly affected by temperature increase. Aside from this, salt also increases the temperature at which water boils. With 100 grams of almost-boiling water (around 200 to 212 degrees F), you can add around 40 grams of salt before it becomes saturated.
How do you know when a solution is saturated?
It's easy to tell if a solution is unsaturated, saturated, or supersaturated by adding a very small amount of solute. If the solution is unsaturated, the solute will dissolve. If the solution is saturated, it won't. If the solution is supersaturated, crystals will very quickly form around the solute you've added.
How do you find the saturation of a solution?
Substances That Won't Dissolve in Water Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .
How to dissolve potassium iodide in water?
Dissolve 6 grams of potassium iodide in distilled water. Fill a clean beaker or flask with 200 mL (0.85 c) of distilled water. Then, use a scale and scooper to weigh out 6 grams of potass ium iodine. Pour the potassium iodine carefully into your water. Potassium iodine comes in liquid, tablet, or powder form.
How to make iodine iodide?
Heat your water and iodine on a hot plate while stirring. Place your beaker or flask on a hot plate and turn it on. Set it to the lowest heat setting available. While the water heats, use a glass mixing rod to stir the solution. Continue stirring until the iodide and iodine is thoroughly mixed into the water.

What is iodine used for?
There are a wide variety of iodine solutions used for chemical tests, medical treatments, and sterilization. While each solution calls for a different recipe, all of them require potassium iodide and iodine crystals. Mix standard solutions in distilled water, and tinctures of iodine in ethyl alcohol.
