Place the following solutions in order of increasing osmotic pressure.
I.0.15 M C₂H₆O₂
II.0.15 M MgCl₂
III.0.15 M NaCl

Question

Place the following solutions in order of increasing osmotic pressure. I.0.15 M C₂H₆O₂ II.0.15 M MgCl₂ III.0.15 M NaCl A)III < I < II B)II < III < I C)I < II < III D)II < I < III E)I < III < II

Quizplus · Accepted Answer

Osmotic pressure depends on the concentration of solute particles. MgCl2 dissociates into 3 ions, NaCl into 2 ions, and C2H6O2 does not dissociate, so the order is I < III < II.
