Match the column (Solute in water vs Von't Hoff factor considering complete dissociation) — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

For complete dissociation ($\alpha = 1$), the van't Hoff factor $i$ equals the number of ions produced per formula unit ($n$). Glucose is a non-electrolyte ($n=1, i=1.0$, Q). NaCl dissociates into 2 ions ($i=2.0$, P). $\text{MgCl}_2$ dissociates into 3 ions ($i=3.0$, R). $\text{AlCl}_3$ dissociates into 4 ions ($i=4.0$, S). Therefore, correct answer is A-Q, B-P, C-R, D-S.
