iodine is poorly soluble in water, with 1 gram dissolving in 3450ml at 20 degree Celsius and 1280 ml at 50 degree Celsius. by contrast with chlorine the formation of the hypohalite ion (IO-) in neutral aqueous solutions of iodine is negligible. solubility in water is greatly improved if the solution contains dissolved iodides such as hydroiodic acid, potassium iodide or sodium oxide. dissoled bromides also improve water solubility of iodine. iodine is soluble in a number of organic solvents, including ethanol, diethyl ether, chloroform, acetic acid, glycerol, benzene, carbon tetrachloride, carbon disulphide

Not very much. If you want to increase the solubility add a salt containing I-. This way you will form the highly soluble complex ion I3(-).

Yes, it is.
But you can improve its solubility by adding I -saltsin the water.
