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 $\Delta P$.
(a)Sucrose will give minimum value of $\Delta P$.
$\Delta P = {P^0} - {P_s}$
${P_s} = {P^0} - \Delta P$ is maximum.
