Question

Do you expect potassium iodide to be soluble in cyclohexane

Answer 1

Answer is: no, potassium iodide has low solubility in cyclohexane.
Potassium iodide (KI) is ionic compound, salt, that dissolve good in polar solvents (for example water), but it is very low soluble in non-polar solvents (in this example cyclohexane C₆H₁₂).
Cyclohexane has zero net polarity, because it is a symmetric molecule, with sp2 hybridization of carbon.

Answer 2

Answer:

KI is not expected to be soluble in cyclohexane

Explanation:

• KI is an ionic solid. In crystal of KI, $K^{+}$ and $I^{-}$ ions are held together through coloumbic attraction force.
• Cyclohexane is a non-polar solvent. Only van der waal force exists between cyclohexane molecules.
• During dissolution of KI in cyclohexane, cyclohexane molecules exerts only van der waal force to KI molecules.
• But this weak van der waal force cannot overcome the coloumbic attraction force exists between KI molecules during dissolution.
• Hence KI is not expected to be soluble in cyclohexane.
