Question

The attachment won't post. The question was if solutions A and B are separated by a selectively permeable membrane. The membrane is permeable to glucose and permeable to NACL. Solution A is a 400 ml solution composed of 300 mM glucose and 200 mM NaCl. Solution B is a 400 ML solution on the opposite side of the membrane, composed of 0 mM glucose and 500 mM NaCl.

Enter the concetrations of NACL and glucose in each solution after the system is allowed to reach equilibrium: in mM:

Glucose in solution A:

NaCl in solution A:

Glucose in solution B:

NaCl in solution B:

Answer 1

At Equilibrium the concentration of glucose and Nacl must be same on either side of the membrane.

1mM=0.001moles/L

[Glucose]A=300mM=300*0.001 moles/L=0.3 moles/L

[Nacl]A=200mM=200*0.001 mol/L=0.2moles/L

[Glucose]B=0

[Nacl]B=500mM=0.5 mol/L

So at equilibrium, [Glucose]eq=0.3+0/2=0.15 mol/L=0.15*10^3 mmol/L=150mM

                           [Nacl]eq=0.2+0.5/2=0.35 mol/L=0.35*10^3 mmol/L=350mM

Glucose in solution A:150mM

NaCl in solution A:350mM

Glucose in solution B:150mM

NaCl in solution B: 350mM
