* Ionic Compound: CaCl₂ is an ionic compound, meaning it readily dissociates into its constituent ions (Ca²⁺ and 2Cl⁻) when dissolved in water.
* Free Ions: These free ions are the key to conductivity. They can move freely within the solution, carrying electrical charge.
* Strong Electrolyte: CaCl₂ is a strong electrolyte, meaning it dissociates almost completely in water. This results in a high concentration of free ions, further increasing conductivity.
In contrast, distilled water has very low conductivity because it contains very few ions. When CaCl₂ is dissolved in distilled water, the conductivity increases dramatically due to the presence of the highly mobile ions.
Therefore, a solution of CaCl₂ in distilled water will exhibit a high conductivity value.
