can exist as several distinct hydrated coordination complexes. A aqueous solution of one specific is — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

First, find $i = \frac{\Delta T_f}{K_f \times m} = \frac{3.72}{1.86 \times 1} = 2$. An $i$ value of 2 means the complex dissociates into exactly 2 ions in solution. The only isomer that furnishes exactly one complex cation and one chloride anion ($1+1=2$) is $[Pt(H_2O)_3Cl_3]Cl \cdot 3H_2O$.
