The osmotic pressure of equimolar solutions of glucose, sodium chloride and barium chloride will be in the order :

Answer»

`BaCl_(2) GT NaCl gt ` glucose
`BaCl_(2) gt` glucose `gt` NaCl
Glucose `gt BaCl_(2) gt NaCl`
`NaCl gt BaCl_(2) gt` glucose

Solution :Osmotic PRESSURE DEPENDS upon the number of particles given by solute. Glucose remains undissociated, SODIUM chloride gives `(NA^(+)+Cl^(-))^(2)` mole particlesper mole and barium chloride gives `(Ba^(2+), 2Cl^(-))`3 mole particles pre mole. Therefore, correct order is A.
