A) 0.5 M Glucose on left; 0.3 M Glucose on the right B) 0.3 M Glucose on left; 0.5 M Glucose on the right C) 0.3 M Na+ on left; 0.5 M Na+ on the right D) 0.5 M Na+ on left; 0.3 M Na+ on the rightExplanation / Answer
concentration separated by a semipermeable membrane
The rate of diffusion will be more when the osmotic pressure gradient is more.
Osmotic pressure = iRT
Where,
i = number of ions created by dissociation of solute molecules
R = ideal gas constant
T = absolute temperature in K
C = molar or molal concentration
All the options have same solute I.e Na+
Solvent is more in concentration in right side (less osmotic pressure on right side)
Hence diffusion will be from right to left.
Glucose has more molecular wt. hence more osmotic pressure than same molarity of Na+.
Rest is same.
