MCQ
If $\alpha $ is the degree of ionization, $C$ the concentration of a weak electrolyte and ${K_a}$the acid ionization constant, then the correct relationship between $\alpha ,\,\,C$ and ${K_a}$is
- A${\alpha ^2} = \sqrt {\frac{{{K_a}}}{C}} $
- B${\alpha ^2} = \sqrt {\frac{C}{{{K_a}}}} $
- ✓$\alpha = \sqrt {\frac{{{K_a}}}{C}} $
- D$\alpha = \sqrt {\frac{C}{{{K_a}}}} $
