Question

arrange in increasing order of osmotic pressure 0.1M sucrose 0.5M glucose and 0.1M NaCl

Answer 1

$$\begin{gathered} Osmoticpressure\mathrm{\pi }=\mathrm{icRT} \\ \mathrm{As}\mathrm{R}\mathrm{and}\mathrm{T}\mathrm{are}\mathrm{constant},\mathrm{the}\mathrm{value}\mathrm{of}\mathrm{\pi }\mathrm{depends}\mathrm{on}\mathrm{i}\mathrm{and}\mathrm{C} \\ {\mathrm{\pi }}_{\mathrm{sucrose}}=1\times 0.1=0.1 \\ {\mathrm{\pi }}_{\mathrm{glucose}}=1\times 0.5=0.5 \\ {\mathrm{\pi }}_{\mathrm{NaCl}}=2\times 0.1=0.2 \\ \mathrm{So}\mathrm{the}\mathrm{increasing}\mathrm{order}\mathrm{is} \\ {\mathrm{\pi }}_{\mathrm{glucose}}<{\mathrm{\pi }}_{\mathrm{sucrose}}<{\mathrm{\pi }}_{\mathrm{NaCl}} \end{gathered}$$
