AIPMT MAINS 2009 Chemistry Colligative Properties MCQ Question
A 0.0020 m aqueous solution of an ionic compound Co(NH₃)₅(NO₂)Cl freezes a.00732°C. Number of moles of ions which 1 mol of ionic compound produces on being dissolved in water will be (Kf = -1.86°C/m)
3
4
1
2
Correct Answer
Detailed Explanation
The freezing point depression is calculated using ΔTf = i × Kf × m. Solving for i gives the number of ions. Here, i = 2, indicating the compound dissociates into 2 ions.
