The coefficient that corects the observed osmotic pressure for an imperfectly semi-permeable membrane is A) $\phi$ B) $\sigma$ C) L_p D) p E) Lp $\sigma$

Question

Quizplus · Accepted Answer

The coefficient that corrects the observed osmotic pressure for an imperfectly semi-permeable membrane is represented by $\sigma$, known as the reflection coefficient. This coefficient accounts for the membrane's selectivity in allowing certain solutes to pass through while reflecting others, thus affecting the observed osmotic pressure.
