Chemistry - Liquid Solution Question with Solution | TestHub

The osmotic pressure of a solution is given by $\pi =iCRT$.

For the barium chloride solution:
${\pi }_1=i_{1}CRT=0.62$ atm

For the glucose solution:
${\pi }_2=i_{2}CRT=0.24$ atm

Since glucose is a non-electrolyte, its van't Hoff factor $i_2=1$.

Therefore, $CRT=0.24$ atm.

Substituting the value of $CRT$ into the equation for barium chloride:
$i_1\times 0.24=0.62$

$i_1=\frac{0.62}{0.24}=\frac{31}{12}\approx 2.58$

The van't Hoff factor of barium chloride is $2.58$.

Answer: $2.58$
