What is the approximate value of the van’t Hoff factor in this case?

1. Close to 1
2. Around 2
3. Nearly 1/2
4. Impossible to determine

Correct answer: Around 2

Solution

The van’t Hoff factor indicates the effective number of particles formed in solution. Since the situation corresponds to dissociation into about two particles, the factor is approximately 2. Therefore, the correct answer is "Around 2".
