A) 0.1 RT
B) 0.11 RT
C) 1.1 RT
D) 0.01 RT
Correct Answer: B
Solution :
\[{{\left[ H \right]}^{+}}\,\,=\,\,C\alpha \] \[{{10}^{-2}}\,=\,\,0.1\times \alpha \,\,\,\,\,\,\,\,\,\,\,\left\{ \begin{matrix} \because \,\,pH\,\,=\,\,2 \\ \therefore \,\,\,\,{{\left[ H \right]}^{+}}\,\,=\,\,{{10}^{-2}} \\ \end{matrix} \right.\] \[\alpha =0.1\] \[i=1-\alpha +n\alpha \] \[\Rightarrow \,\,\text{ }1\,\,-\,\,a\,\,+\,\,2\alpha \] \[i=1+\alpha =1.1\] \[\pi \,\,=\,\,iCRT.\]
