• # question_answer pH of a 0.1 M monobasic acid is measured to be 2. Its osmotic pressure at a given temperature T K is- A) 0.1 RT              B) 0.11 RTC) 1.1 RT              D) 0.01 RT

${{\left[ H \right]}^{+}}\,\,=\,\,C\alpha$ ${{10}^{-2}}\,=\,\,0.1\times \alpha \,\,\,\,\,\,\,\,\,\,\,\left\{ \begin{matrix} \because \,\,pH\,\,=\,\,2 \\ \therefore \,\,\,\,{{\left[ H \right]}^{+}}\,\,=\,\,{{10}^{-2}} \\ \end{matrix} \right.$             $\alpha =0.1$ $i=1-\alpha +n\alpha$ $\Rightarrow \,\,\text{ }1\,\,-\,\,a\,\,+\,\,2\alpha$ $i=1+\alpha =1.1$ $\pi \,\,=\,\,iCRT.$
