Question

State True or False.

For a solution of $Al{Cl}_3$ in water, the Van't Hoff factor (i) is greater than 1.

• A. True
• B. False

Answer 1

The correct option is A True

For a solution of $Al{Cl}_3$ in water ,the Van't Hoff factor (i) is greater than 1 due to hydrolysis.

$Al{Cl}_3+3H_{2}O\to Al(OH{)}_3+3C{l}^{-}$

The vant Hoff factor is the ratio of actual number of particles to number of particles for no ionization.

As the number of particles increases due to hydrolysis, the vant Hof factor is more than 1.

Hence, the given statement is true.
