Question
Which of the following aqueous solutions should have the highest osmotic pressure?
Options
A.0.011 M AlCl3 at 50oC
B.0.03 M NaCl at 25oC
C.0.012 M (NH4)2SO4 at 25oC
D.0.03 M NaCl at 50oC
Solution
π = i C R T
π ∝ i C T
(1) 0.011 × 4 × 323 = 14.2
(2) 0.03 × 2 × 298 = 17.8
(3) .012 × 3 × 298 = 10.7
(4) 0.03 × 2 × 323 = 19.4
option (4) has max value of π
