A scientist interested in modeling the effects of proteins in biologic solutions set up two rigid compartments separated by an artificial membrane. The membrane was permeable to water, ions, and small organic molecules but was almost impermeable to albumin. The figure shows the initial conditions of her experiment. After the system had reached equilibrium, what changes in sodium and chloride concentrations, if any, would be noted in the inner compartment?


Inner compt: 140mEq/L Na+, 120mEq/L Cl-, 20mEq/L albumin
Outer compt: 140mEq/L Na+, 140mEq/L Cl-

A. Sodium concentration higher/chloride concentration higher
B. Sodium concentration higher/chloride concentration lower
C. Sodium concentration higher/chloride concentration unchanged
D. Sodium concentration lower/chloride concentration higher
E. Sodium concentration lower/chloride concentration lower
F. Sodium concentration unchanged/chloride concentration lower
G. Sodium concentration unchanged/chloride concentration unchanged

no-one wants to answer my Q

A???? since albumin being the non permeable component is the one determinign the movement of water and solutes... so more water and that would draw more sodium and chlorides?

e.

boggart what is the conc of cl in the outer compartment
?????????

140mEq/L in the outer compartment for chloride.

E..

the answer is A

but I thought it would be B...

im lost. are u sure about the answer? ( is it a textbook one?)

its from usmlesteps123.com

remember it says INNER compartment
