MCQ
Lowering of vapour pressure is highest for
  • A
    Urea
  • B
    $0.1\,\,M$ glucose
  • C
    $0.1\,\,M\,MgS{O_4}$
  • ✓
    $0.1\,\,M\,BaC{l_2}$
✓

Answer

Correct option: D.
$0.1\,\,M\,BaC{l_2}$
d
(d)$\frac{{{P^0} - {P_s}}}{{{P^0}}} = {\rm{molality}}\, \times {\rm{(1 - }}\alpha + x\alpha + y\alpha )$ the value of ${P^0} - {P_s}$ is maximum for $BaC{l_2}$.
