Which has maximum osmotic pressure at temperature `T`? a. `100 mL` of `1 M` urea solution b. `300 mL` of `1 M` glucose solution c. Misture of `100 mL` of `1 M` urea solution and `300 mL` of `1 M` glucose solution d. All are isotonic |
|
Answer» d. All are isotonic Osmotic pressure `(pi)` depends upon the concentration of solution, i.e., `pi=C_("effective")RT` For (a), `C_("effective")= 1 M` (since it is non-electrolytic solution) For (b), `C_("effective")= 1 M` (since it is non-electrolytic solution) For c, `C_("effective")= [100/(100 +300) xx 1 +(300)/(100 +300) xx1] =1 M` |
