Frequently Asked Questions

Are colligative-property problems covered for both ideal and real solutions?+

Yes. Each colligative property is derived for ideal solutions, then corrected with the van't Hoff factor (i) for associating/dissociating solutes — with worked examples for NaCl, K2SO4, and acetic-acid dimers.

Is Henry's law applied to gas solubility?+

Yes. Henry's law is derived in both pressure and mole-fraction forms, with applications to deep-sea diving, blood gases, and fizzy drinks (the standard NEET context).

Do the notes cover positive and negative deviations from Raoult's law?+

Yes — both deviations are explained via intermolecular forces, with vapour-pressure curves drawn for each case and the corresponding sign of ΔH_mix and ΔV_mix.
