Column-I (solute) Column-II (van't Hoff factor, $i$ )

(A) AlCl₃ if $α = 0.8$ (P) $i = 3.4$

(B) BaCl₂ if $α = 0.9$ (Q) $i = 2.8$

(C) Na₃PO₄ if $α = 0.9$ (R) $i = 3.8$

(D) K₄[Fe(CN)₆] if $α = 0.7$ (S) $i = 3.7$

TestHub · Accepted Answer

i = 1 − α + n α For AlCl 3 ​ ; i = 1 − 0.8 + 4 × 0.8 = 0.2 + 3.2 = 3.4 For BaCl 2 ​ ; i = 1 − 0.9 + 3 × 0.9 = 2.8 For Na 3 ​ PO 4 ​ ; i = 1 − 0.9 + 4 × 0.9 = 3.7 For K 4 ​ [ Fe ( CN ) 6 ​ ] ; i = 1 − 0.7 + 5 × 0.7 = 3.8
