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.

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
How do you separate iodine from ammonium chloride?
first you take water in a beaker and put the mixture in it.you will see that ammonium chloride will dissolve in water because it is highly soluble in water and iodine is not so it won't dissolve. However, the solubility of elemental iodine in water can be increased by the addition of potassium iodide.you can then filter out the mixture so the iodine when you filter will stay on the filter paper. you have got your iodine separated.now for ammonium chloride, you can do evaporation or distillation. To get back water you can do distillation and get distilled water.
What is the reason behind using 40 g of potassium iodide and 12.7 g of iodine to prepare 0.1 N of iodine?
- The atomic weight of iodine is 126,90447; for a 0,1 N solution, dividing by 10 the result is 12,69. - The iodide (KI) is added to increase the solubility of iodine in water or alcohol.
Why the solubility of iodine in water increases as the concentration of potassium iodide increases?
The 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. by tarun das
What happens when iodine and water get mix together?
A iodine solution in water.
How do you enhance the solubility of iodine?
The solubility of iodine in water is increased adding potassium iodide.
How do you enhance the solubility of iodine in water?
To enhance the solubility of iodine in water, you can increase the temperature of the water as iodine is more soluble in hot water. Stirring or agitating the solution can also help by increasing the surface area and facilitating the contact between iodine and water molecules. Additionally, adding a solubility-enhancing agent like potassium iodide can significantly increase the solubility of iodine in water.
Do water and iodine form a solution?
Iodine is very low soluble in water; adding potassium iodide the solubility is higher.
What is iodine solubility?
Iodine is highly soluble in water. It is also soluble in iodine solutions, chloroform, carbon tetrachloride and carbon disulphide among others.

Is solubility a hydrogen bonding?
Based on the grammar of your question, you have no idea what solubility is. Solubility- the degree to which a substance can dissolve in a solvent(usually water). Hydrogen bonding is an intermolecular force of attraction that decreases relative solubility.
What is the description of solubility?
Solubility is the ability of a solute to dissolve in a solvent in order to form a homogeneous solution. Relative solubility refers to the solubility of different substances.

How do you separate iodine from sodium chloride?
Iodine is not contained in Sodium Chloride, so can not be removed from it. I am thinking you wish to separate a mixture of Iodine and Sodium Chloride. Heat the mixture to 114C and the iodine will melt. Iodine can be vaporized and distilled. Under certain conditions, Iodine can react with other chemicals to create unstable explosive compounds. So be careful out there.
Does the solubility of solute increase in hot or cold water?
The solubility of gas increases in cold water. The solubility of solid increases in hot water.
Is the relationship between the temperature of water and the solubility of a gas in it a direct or inverse relationship Explain?
The temperature of water and the solubility of a gas are in an inverse relationship; gases are more soluble at low temperatures.
