Chemistry - Ionic Equilibrium Question with Solution | TestHub

$\text{K}\text{=}\frac{{\text{α}}^{\text{2}}\text{C}}{\text{1}-\text{α}}\text{;}\text{1}-\alpha \approx 1$
$\therefore \text{K}\text{=}{\text{α}}^{\text{2}}\text{C}\text{=}{\left[\frac{\text{0}\text{.01}}{\text{100}}\right]}^{\text{2}}\text{×}\text{1}$
$=1\times 10^{-8}$.
