membrane is permeable to water but not to Na+ or Cl-. Initially,
a. water diffuses from compartment B to compartment A.
b. Na+ diffuses from compartment B to compartment A.
c. Na+ diffuses from compartment A to compartment B.
, d. water diffuses from compartment A to compartment B. - ANSWER: d. water diffuses from
compartment A to compartment B.
A beaker is divided into two compartments by a semipermeable membrane. Compartment A
contains a 20% NaCl solution and compartment B contains a 50% NaCl solution. The
membrane is permeable to water but not to Na+ or Cl-. At equilibrium, the:
a. volume of water in compartment A will be greater than the volume in compartment
B.
b. volume in both compartments A and B will be equal.
c. concentration of compartment A will decrease.
d. volume in compartment B will be greater than the volume in compartment A. - ANSWER: d. volume
in compartment B will be greater than the volume in compartment A.
