Chemistry - Liquid Solution Question with Solution | TestHub

Osmotic pressure: $\pi =iCRT$, where $i$ = number of particles after dissociation.

K₄[Fe(CN)₆] → 5 ions $\Rightarrow \pi >4CRT$

CH₃COOH weak electrolyte $\Rightarrow i<2$

CaCl₂ ($i\approx 3$) and Na₃PO₄ ($i\approx 4$) $\Rightarrow$ higher osmotic pressure
