NaI is an ionic compound which can dissolve in water due to the polar nature of water molecules. [example here]. Iodine is made up of molecules of I2, which individually have no dipole moment (I-I bond has no dipole as both iodine atoms have same electronegativity).Iodine is covalent in nature and therefore, it does not dissolve in water which is polar. In KI solution, iodine reacts to form KI3 which is ionic in nature. Therefore, it becomes soluble in water.Elemental iodine is slightly soluble in water, with one gram dissolving in 3450 ml at 20 °C and 1280 ml at 50 °C; potassium iodide may be added to increase solubility via formation of triiodide ions, among other polyiodides. Nonpolar solvents such as hexane and carbon tetrachloride provide a higher solubility.

Is sodium iodide soluble in water?
Why is iodide more soluble in water?
Iodine is covalent in nature and therefore, it does not dissolve in water which is polar. In KI solution, iodine reacts to form KI3 which is ionic in nature. Therefore, it becomes soluble in water.

What is iodine solubility in water?
Elemental iodine is slightly soluble in water, with one gram dissolving in 3450 ml at 20 °C and 1280 ml at 50 °C; potassium iodide may be added to increase solubility via formation of triiodide ions, among other polyiodides. Nonpolar solvents such as hexane and carbon tetrachloride provide a higher solubility.
What is the reaction of sodium and iodine?
Reactions with sodium
Hot sodium will also burn in bromine or iodine vapor to produce sodium bromide or sodium iodide. Each of these reactions produces an orange flame and a white solid.
Why is iodide soluble?
Iodide, being large, is less hydrophilic compared to the smaller anions. One consequence of this is that sodium iodide is highly soluble in acetone, whereas sodium chloride is not. The low solubility of silver iodide and lead iodide reflects the covalent character of these metal iodides.
Why does iodine has a much lower melting point than sodium iodide?
basically, the iodine ion is larger so the forces of attraction between it’s protons and electrons are weak while the sodium ion is small and is positively charged so it attracts the iodide ion’s electron cloud.
Is sodium iodide neutral?
The iodide anion is the extremely weak conjugate base of a strong monoprotic acid (HI), so it also has no effect on the solution pH. Therefore, this solution will have a neutral pH of 7 at a temperature of 25 degrees Celsius.

Iodine (I) and water – Lenntech
Inorganic iodines are highly water soluble. Why is iodine present in water? Iodine ends up in surface waters naturally through rains and water evaporation.
Difference Between Sodium Chloride and Sodium Iodide

Iodine, for example, is slightly soluble in water and gives a yellowish-brown solution. Brown solutions are also formed with alcohol, ether, ketones, and other …
Sodium iodide – Wikipedia
Sodium iodide (chemical formula NaI) is an ionic compound formed from the chemical reaction of sodium metal and iodine. Under standard conditions, it is a …
Is iodine polar or non polar?
IODINE: Iodine forms a diatomic non-polar covalent molecule.
Why is solution of iodine prepared in potassium iodide and not in water?
Iodine (I₂) itself is very poorly soluble in water. As a diatomic molecule with two identical atoms, it is totally non-polar; it therefore dissolves well in organic solvents but not in water.
Is I2 polar or non polar?
iodine (I2) Notice the symmetry of the molecule: When divided, the top and bottom as well as the left and right are mirror images of one another. One also knows the molecule is non polar because the bond is non polar.

Is iodine and iodide the same?
Also called iodide, iodine is a type of mineral that’s naturally found in the earth’s soil and ocean waters. Many salt water and plant-based foods contain iodine, and this mineral is most-widely available in iodized salt. It’s important to get enough iodine in the diet.
What happens when iodine reacts with water?
Iodine reacts with water to produce hypoiolite, OI–. The pH of the solution determines the position of the equilibrium. Iodine is not reactive towards with oxygen or nitrogen. However, iodine does react with ozone, O3 to form the unstable yellow I4O9.
Does iodine dissociate in water?
Although non-polar molecular iodine cannot dissolve in water, it reacts with iodide ion to form something that can: the triiodide ion. When iodide and iodine meet at water/chloroform-hexane surfaces, the triiodide ion formed dissolves in the water, not the non-polar solvent mixture.

What will happen if we combine the solution of sodium iodide and the solution of lead II nitrate?
When these two solutions are mixed, the lead(II) cations, Pb2+ , and the iodide anions, I− , will bind to each other and form lead(II) iodide, an insoluble ionic compound. The other product of the reaction is aqueous sodium nitrate, NaNO3 , which will exist as ions in solution.
How do you separate sodium iodide?
Sublimation is the best method for separating iodine from common salt (NaCl). Since iodine is sublimable, it will change to vapour state directly from solid when heated slightly and the iodine vapours can be collected while common salt remains as such. Answer: Best way is sublimation.
Is NaI soluble or insoluble?
Sodium iodide is a water-soluble ionic compound with a crystal lattice.
Is Ki soluble in water?
What happens when a solution of sodium iodide is mixed with a solution of chlorine?
> Chlorine reacts with sodium iodide to make iodine and sodium chloride solution.

Is iodine soluble or slightly soluble in water?
Iodine, for example, is slightly soluble in water and gives a yellowish-brown solution.
Is iodine stable in water?
Iodine is only slightly soluble in water but dissolves readily in a solution of sodium or potassium iodide. Tincture of iodine is a solution of iodine and potassium iodide in alcohol. Iodine also dissolves in carbon disulfide, carbon tetrachloride, and chloroform, giving a deep violet solution.
