Question

For a non-electrolytic solution, van't Hoff factor is equal to:

• A. $0$
• B. $1$
• C. $2$
• D. $0<i\le 1$

Answer 1

The correct option is B $1$

Van't Hoff factor is more than 1 for the strong electrolytes which will dissociated and forms more than one ion.

Van't Hoff factor for weak electrolytes and non-electrolytes is equal to 1

Van't Hoff factor is less than 1 for the molecules which will tend to associate to form dimer molecules.
