Question

The Van't Hoff factor for a dilute aqueous solution of glucose is :

• A. $Zero$
• B. $1.0$
• C. $1.5$
• D. $2.0$

Answer 1

Answer: (B)

$1.0$

Glucose is a non electrolyte. It does not dissociate in ions.
The vant Hoff factor (i) for dilute aqueous solution of glucose is $i=\frac{n\left(observed\right)}{n\left(theoretical\right)}=\frac{\left(1\right)}{1}=1$
