Vedclass · Answer

(C) The osmotic pressure $\pi$ is given by $\pi = iCRT$,where $i$ is the van't Hoff factor,$C$ is molarity,$R$ is the gas constant,and $T$ is temperature.For $(I)$ $0.01\, M$ glucose: $i = 1$,so $\pi_I = 1 	imes 0.01 	imes RT = 0.01RT$.For $(II)$ $0.01\, M$ $KNO_3$: $i = 2$ (dissociates into $K^+$ and $NO_3^-$),so $\pi_{II} = 2 	imes 0.01 	imes RT = 0.02RT$.For $(III)$ $0.01\, M$ acetic acid in benzene: Acetic acid dimerizes in benzene,so $i \approx 0.5$,thus $\pi_{III} = 0.5 	imes 0.01 	imes RT = 0.005RT$.Comparing the values: $\pi_{III} (0.005RT) Since $\pi_{II} > \pi_I$,solution $(II)$ is hypertonic with respect to solution $(I)$.

Consider the following solutions at $25\,^oC$:
$(I)$ $0.01\, M$ aqueous solution of glucose
$(II)$ $0.01\, M$ aqueous solution of $KNO_3$
$(III)$ $0.01\, M$ solution of acetic acid in benzene
