Which of the following pairs have a vant Hoff i factor of 2?

Question

Quizplus · Accepted Answer

The vant Hoff i factor is a measure of the number of particles in a solution that contribute to colligative properties. For a binary salt like sodium chloride or magnesium sulfate, the i factor is 2, because each salt molecule will dissociate into two ions in solution. Therefore, choice B, which contains both sodium chloride and magnesium sulfate, would have a vant Hoff i factor of 2. The other choices contain either non-dissociating species (like glucose) or salts that have an i factor other than 2.
