No. Iodine exist as I2, which is formed by the induced dipole-induced dipole interaction. Thus, it is a non-polar compound.
Water, which is a polar solvent, prefers to stay hydrogen bonded then break up iodine. Remember: like dissolves like. This means that non-polar compounds like iodine will dissolve in non-polar solvent such as hexane, which polar compounds such as hydrochlorine gas will dissolve in polar solvents like water.

∙ 11y agoThe I2 molecules in iodine are not very soluble in water because they are not alike. I2 is non-polar whereas H2O is polar. But KI solution contains I- ions which combine with the I2 molecules to form I3- ions because these are charged they dissolve in the water which is a polar solvent.

Explain the relative solubility of iodine in water?
Iodine itself, I2 is not very soluble in water. However, the solubility of iodine can be greatly increased by adding potassium iodide to the reaction. The potassium iodide is broken apart into K+ and I-. The potassium ion is then dissolved into the water, and the iodine ion reacts with the I2 to form I3-. This I3- molecule is soluble in water. Therefore, the solubility is relative because I2 is not very soluble, but I3- is soluble, and both are made of nothing but iodine. Hope this helps.
Why is KI used in estimation of iodine in tincture iodine?
this is because iodine is not soluble in water and it is soluble in potassiuim iodide. so KI is used as a solvent, and the resulting potassium iodate is soluble in watre so we can determine iodine in the ticture.
What is tincture of iodine and what is it used for?
Tincture of iodine is about 5% iodine, potassium iodide, and sodium iodide in ethanol and water. It's a topical antiseptic and disinfectant.
What is the role of potassium iodide in the formulation of strong iodine solution?
The role of KI in the preparation of strong iodine solution is to enhance the solubility of iodine crystals in water. Iodine is generally not soluble in water. The KI is added to help the iodine to be dissolved. -College Chemistry professor
What is the composition of tincture of iodine?
Tincture of iodine or iodine tincture is an antiseptic, it is also called weak iodine solution. It is usually 2-7% elemental iodine, along with potassium iodide or sodium iodide, dissolved in a mixture of ethanol and water.
What makes iodine soluble in water?
You can make iodine soluble in water by addition of potassium iodide KI
Do water and iodine form a solution?
Iodine is very low soluble in water; adding potassium iodide the solubility is higher.
What is SrI2?
Strontium iodide (SrI2) is a salt of strontium and iodine. It is an ionic, water-soluble, and deliquescent compound that can be used in medicine as a substitute for potassium iodide Strontium iodide (SrI2) is a salt of strontium and iodine.

How do you enhance the solubility of iodine?
The solubility of iodine in water is increased adding potassium iodide.

What is the difference between Iodine bought in a pharmacy and the Iodine stain solution?
The iodine stain solution you're referring to might be Lugol's iodine. This is iodine and potassium iodide in water. The product available in a pharmacy is tincture of iodine which is iodine and potassium iodide in ethanol and water. Please see the links.
Why is ethanol soluble in ether?
Iodine crystals are not soluble in water. This is because Iodine crystals are non-polar. Water is a polar molecule and it therefore cannot attract an one of the iodine atoms since they have an electronegativity of zero.
What is the difference between starch solution and iodine solution?
Starch is composed of amylose and amylopectin, and is not soluble in water due to the presence of amylopectinIodine (I₂) is somewhat soluble in water, but is more soluble in iodide (I⁻) solutions, such as potassium iodide solution (KI).Aqueous iodine molecules (I₂) and iodide ions (I⁻) together will form triiodide ions (I₃⁻), which can react with amylose found in starch to produce a deep-blue colour in the solution. So all of iodide (I⁻), iodine (I₂) and amylose (or starch) are required together to produce the colour.This can be used to test for:Amylose/Starch: Add iodine dissolved in potassium iodide solution to test solution, orIodine: Add starch and potassium iodide solutions to test solution.If the substance being tested for is present, then triiodide ions (I₃⁻) can react with amylose (in starch) to produce a deep-blue colour, that is, a positive result.
Methods of producing iodized salt?
Iodine is added to salt as potassium (sodium) iodide or potassium (sodium) iodate. An iodine deficiency is a source of thyroide diseases or can lead to idiocy.
