Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent. The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration, where adding more solute does not increase the concentration of the solution and begins to precipitate the excess amount of solute. It is an inorganic sodium salt and an iodide salt. This also prevents the backward reaction to occur according to … Answer =  ICl3  (Iodine trichloride)  is  Polar What is polar and non-polar? It also reacts violently with strong oxidants, strong acids and bromine trihalides, producing iodine.
