Question

Answered step-by-step

Problem 102 Medium Difficulty

Iodine $\left(\mathrm{I}_{2}\right)$ is only sparingly soluble in water (left photo). Yet upon the addition of iodide ions (for example, from $\mathrm{KI}$ ), iodine is converted to the triiodide ion, which readily dissolves (right photo):
$$\mathrm{I}_{2}(s)+\mathrm{I}^{-}(a q) \rightleftharpoons \mathrm{I}_{3}^{-}(a q)$$
Describe the change in solubility of $\mathrm{I}_{2}$ in terms of the change in intermolecular forces.

Properties Of Solutions - Intro

In chemistry, a solution is a homogeneous mixture composed of two or more substances. The term "solution" is also used to refer to the resultant mixture. The solution is usually a fluid. The particles of a solute are dispersed or dissolved in the solvent. The resulting solution is also called the solvent. The solvent is the continuous phase.

Natural Tendency Toward Mixing

In physics and thermodynamics, the natural tendency of a system to change its state is its tendency to increase the entropy of the system. It is a measure of the disorder in a system.
