**Freezing Point Depression Activity**Match the following aqueous solutions with the appropriate letter from the column on the right.**Solutions:**1. 0.18 m Ni(NO₃)₂2. 0.25 m ZnSO₄3. 0.20 m CoCl₂4. 0.56 m Sucrose (nonelectrolyte)**Categories:**A. Lowest freezing pointB. Second lowest freezing pointC. Third lowest freezing pointD. Highest freezing point---**Explanation:**Freezing point depression depends on the molality of the solution and the number of particles the compound dissociates into when dissolved in water. Electrolytes, which dissociate into ions, will cause a greater freezing point depression than nonelectrolytes at the same molality.- **Ni(NO₃)₂** dissociates into 3 ions (Ni²⁺ and 2 NO₃⁻).- **ZnSO₄** dissociates into 2 ions (Zn²⁺ and SO₄²⁻).- **CoCl₂** dissociates into 3 ions (Co²⁺ and 2 Cl⁻).- **Sucrose** does not dissociate, so it remains 1 molecule in solution.Using the van 't Hoff factor (i), which represents the number of particles into which a solute dissociates, we can predict:1. 0.18 m Ni(NO₃)₂ (i = 3)2. 0.25 m ZnSO₄ (i = 2)3. 0.20 m CoCl₂ (i = 3)4. 0.56 m Sucrose (i = 1)Multiplying molality by the van 't Hoff factor:- **0.18 m Ni(NO₃)₂** : 0.18 * 3 = 0.54- **0.25 m ZnSO₄** : 0.25 * 2 = 0.50- **0.20 m CoCl₂** : 0.20 * 3 = 0.60- **0.56 m Sucrose (nonelectrolyte)** : 0.56 * 1 = 0.56Thus, the solutions in order from lowest to highest freezing
