MCQ
Which solution will show the maximum vapour pressure at $300\,K$
  • $1\,M$  $C{_{12}}{H_{22}}{O_{11}}$
  • B
    $1\,M$  $C{H_3}COOH$
  • C
    $1\,M$ $CaC{l_2}$
  • D
    $1\,M$  $NaCl$

Answer

Correct option: A.
$1\,M$  $C{_{12}}{H_{22}}{O_{11}}$
a
(a)Sucrose will give minimum value of $\Delta P$.

$\Delta P = {P^0} - {P_s}$

${P_s} = {P^0} - \Delta P$ is maximum.
