Δ Tf propto i, A l2(S O4)3( aq ) Leftrightarrow 2 A l3++3 S O42- [Total ions 5 ,thus, i=5] Al 2( SO 4)3 will exhibit largest freezing point depression due to the highest value of i.

Q. Of the following $0.10 m$ aqueous solutions, which one will exhibit the largest freezing point depression?

$N a Cl$

$C_{6} H_{12} O_{6}$

$A l_{2} (S O_{4})_{3}$

$B a C l_{2}$

$Δ T_{f} \propto i, A l_{2} (S O_{4})_{3} (a q) \Leftrightarrow 2 A l^{3 +} + 3 S O_{4}^{2 -}$
[Total ions 5 ,thus, $i = 5]$
$A l_{2} (S O_{4})_{3}$ will exhibit largest freezing point depression due to the highest value of $i$ .
