What Happens When Iodine And Calcium Ionic Compound Is Dissolved In Water?

When iodine and calcium ionic compound (calcium iodide, CaI2) is dissolved in water, the compound dissociates into its constituent ions. The calcium ion (Ca2+) and iodide ion (I-) become hydrated, meaning they are surrounded by water molecules due to their charges.

The dissolution of calcium iodide in water is an exothermic process, meaning it releases heat energy. This is because the hydration of the ions releases more energy than is required to break the original ionic bonds.

Overall, the resulting solution will consist of hydrated calcium ions (Ca2+(aq)), hydrated iodide ions (I-(aq)), and water molecules (H2O(l)).
