A) \[\alpha =\frac{{{K}_{a}}}{C}\]
B) \[\alpha =\sqrt{\frac{{{K}_{a}}}{C}}\]
C) \[\alpha ={{K}_{a}}.C\]
D) \[\alpha =\frac{\sqrt{{{K}_{a}}}}{{{C}^{2}}}\]
Correct Answer: B
Solution :
The relationship between ionization and change in concentration of any weak electrolyte is represented by \[\alpha =\sqrt{\frac{Ka}{C}}\] where \[\alpha \] = degree of dissociation C = molar concentration \[{{K}_{a}}\] = ionization constant
