Potassium iodide (KI) is a strong electrolyte, meaning it dissociates completely into its ions when dissolved in water. This results in a high conductivity.

Here's why:

* Ionic nature: KI is composed of a potassium cation (K+) and an iodide anion (I-).

* Dissociation in water: When KI dissolves in water, the strong electrostatic attraction between the water molecules and the ions overcomes the ionic bond holding the KI molecule together. The ions become surrounded by water molecules and separate, creating a solution with freely moving charge carriers (ions).

* Charge carriers: These free ions can carry electrical current, making the solution highly conductive.

Quantitative values for conductivity depend on the concentration of the solution and temperature.

Here's a general comparison:

* Pure water: Very low conductivity due to the limited presence of H+ and OH- ions.

* Dilute KI solution: High conductivity compared to pure water.

* Concentrated KI solution: Even higher conductivity due to more ions per unit volume.

Note: Conductivity is not the same as solubility. While KI is highly soluble in water, its conductivity is a separate property related to the ability of its ions to carry electrical current.
