Lithium iodide, or lii, is a compound of lithium and iodine. Lithium iodide is less soluble in water compared to other group 1 halides due to the larger size of the iodide ion. When exposed to air, it becomes yellow in color, due to the oxidation of iodide to iodine. The hydrates have congruent melting points unlike the … Lii-0. 5 h2o, l i l·o , lii-2h20 and lii·3h20. You could also determine that lii is soluble using the rule that salts … · lithium iodide (lii) is an inorganic compound composed of lithium (li⁺) and iodide (i⁻) ions. The li ion, so the … Here if we see both the elements the cation is the same i. e. The chemical formula is lii. It can participate in various hydrates. It appears as a white to pale yellow crystalline solid and is highly soluble in water and … Lithium iodide is composed of li+1 and i-1 ions. When lii is dissolved in water, the ions are stabilized by water molecules, giving off energy that is greater than the lattice energy of lii. · its to do with the relative values of the enthalpies of hydration compared to the lattice enthalpy. A trend you will find is that ionic compounds with large differences in the radii … The dissolution of lithium iodide is thus exothermic. It crystallizes in the nacl motif. See the table below to see the exact solubility. Lii is soluble in water. Lif is more soluble in water than lii because lif has a higher ionic character due to the smaller size of the fluoride ion compared to the iodide ion, which contributes to its lower … As in the question it has been asked to state the factors why lii is soluble in water but the lif is insoluble. · lithium iodide is a compound composed of lithium and iodine that turns yellow when iodine is oxidized to iodine and exposed to air. · lithium iodide is very soluble in water and forms the following hydrates:
