van't Hoff Factor and Abnormal Molar Mass
Study the van't Hoff factor (i), its calculation for electrolytes and non-electrolytes, and its effect on colligative properties and molar mass determination.
Why this shows up in the exam
You must account for association/dissociation in solutions to correctly solve colligative property problems.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
The van't Hoff factor i for a compound which undergoes dissociation in one solvent and association in other solvent is respectively

A complex salt, [Co(NH₃)₅Cl]Cl₂, dissociates in water. What would be the expected van't Hoff factor (i) for this complex, assuming complete dissociation of the ionic components?
