Q. The order of osmotic pressure of isomolar solution of $BaCl_{2}$, NaCl and sucrose is
A) $BaCl_{2}$ >NaCl>sucrose
B) NaCl>$\ BaCl_{2}$> sucrose
C) Sucrose>NaCl>$\ BaCl_{2}$
D) $BaCl_{2}$ >sucrose>NaCl
Explanation
(a)
The order of osmotic pressure of $BaCl_{2}$ , NaCl and sucrose is
$BaCl_{2}$ >NaCl>sucrose
Since, Ba$Cl_{2}$ gives maximum ion (3 ions) in the solution.
