Why Iodine is almost insoluble in water but it dissolves easily in aqueous solution of KI?

Iodine (I2) reacts with iodide (I-) to form triiodide ion (I3-). Although I2 is insoluble in water, I3-is very soluble, so adding KI will pull I2into solution is I3-.

What are the two method that can be use to separate a mixture of iodine crystal and iron fillings?
Since lead iodide is insoluble in an aqueous solution, you could filter it out using a funnel and filter paper.
What is the name of starch indicators solution?
It is the Iodine dissolved in aqueous Potassium(or Sodium) Iodide
Is iodine dissolves in carbontetrachloride?
yes. iodine will dissolve in carbon tetrachloride
What is the results of carbon tetrachloride and iodine?
Iodine dissolves in carbon tetrachloride giving a purple color medium.
Chlorine gas reacts with aqueous potassium iodide to form solid iodine and aqueous potassium chloride.?
Yes, it is correct.
What is the procedure for the preparation of aqueous iodine solution?
side effect of iodine

What indicator substance is used to test a leaf for starch?
Iodine Solution is used to determine whether starch is present.
What does lugol's iodine?
it is iodine and potassium iodide solution It's a orange colored solution that consists of Iodine and Potassium Iodide and is used to test a substance for starch. If the color of the solution turns black when put on/in the substance, then the substance is positive for starch.
What happens when chlorine gas is added to potassium iodide solution?
When chlorine gas is bubbled into an aqueous solution of potassium iodide, some of the iodide ions are oxidized to iodine. The iodine molecules combine with iodide ions to form brown triiodide ion, I3-. In this demonstration, the aqueous solution is above a layer of carbon tetrachloride, in which iodine is quite soluble. The beautiful violet color of iodine can be seen as the iodine dissolves in the carbon tetrachloride layer. With excess chlorine, iodine reacts to form iodine monochloride, ICl, which is ruby red. The iodine monochloride reacts further to form iodine trichloride, ICl3, which is much lighter in color, causing the solution to be decolorized.
Why does an aqueous solution of iodine not react with potassium chloride?
because it dosent
What is the difference between iodine solution and starch solution?
Starch is insoluble in water. The commonest kind of iodine solution is known as tincture of iodine, which is an orangey-brown liquid. Please see the links.
Why does a aqueous solution of iodine not react with sodium bromide?
Bromine is more reactive than iodine/bromine is higher in the activity series than iodine
What happens when you evaporate an aqueous iodine solution?
It will leave a solid salt, consisting of the ions.
What is the name of starch indicators solution?
It is the Iodine dissolved in aqueous Potassium(or Sodium) Iodide
Why do we rinse the leaf I water?
The leaf was rinsed in water to rehydrate it. Iodine solution is an aqueous solution of iodine/potassium iodine - potassium tri-iodide; water is needed inside the leaf to enable penetration by diffusion.
If chlorine gas is bubbled through an aqueous solution of sodium iodide the result is elemental iodine and aqueous sodium chloride solution what kind of reaction took place?
Single-replacement
